LED-based street lighting market to surpass $2 billion by 2020

USA: Dramatically falling costs and improvements in efficiency are driving increased sales of light emitting diode (LED) lamps for street lighting. Costs have fallen as much as 50 percent over the past two years, and are expected to continue falling.

According to a new report from Pike Research, a part of Navigant’s Energy Practice, by 2015, LEDs will become the second-leading type of lamp for street lights in terms of sales, behind only high pressure sodium lamps. By 2020, the study concludes, LED lamps for street lights will generate more than $2 billion in annual revenue.

“Broader investments in smart city infrastructure by municipal governments will boost smart street lighting projects, as the two go hand in hand,” says research analyst Jesse Foote. “Smart street lighting systems can provide a backbone for other smart city applications, and conversely, a city investing in networking capabilities for smart city applications should also be looking to include better management of street lighting.”

Nearly all smart street lighting projects are still in a pilot phase at the moment, according to the report. The adoption of LED street lights and networked control systems is seriously hindered by the ownership models and tariff structures in place across the United States and in some European and Asian locations as well.

If utility companies own street lighting systems and charge a fixed tariff per light to municipalities, then towns have little financial incentive to pay for upgrading their lights. However, the potential for significant energy savings, reduced emissions and improved quality of service, combined with falling LED prices, means that more and more cities will find this an attractive proposition over time.

iWatt 6-channel LED driver with intelligent digital control engine

USA: iWatt Inc. has announced its latest LED driver for LCD TV backlighting. The new iW7011 is a 6-channel LED driver with a built-in intelligent digital control engine, developed to reduce the bill of materials (BOM) cost and simplify design of edge-lit and direct-lit LCD TVs.

The digital core of the iW7011 provides on-chip control of the DC-to-DC boost circuit, along with precise LED dimming control and all the monitoring and feedback for the LED drivers. It also allows timing delays to be set for dynamic scanning, simplifying design by enabling one part to be used for both 2D and 3D TVs.

The iW7011 uses external LED current sinks and external boost MOSFETs for easy current and voltage scaling (up to 300mA per channel and Vout close to 85V), allowing designers to source one part type to meet requirements spanning medium- to large-size LCD TVs and monitors.

The iW7011 lowers BOM costs by integrating a number of design features. The on-board boost controller provides a high-voltage power supply for the external LED strings. The digital control engine allows real-time control of phase delays (especially relevant for 3D TVs) and manages Vsync synchronization (from 50Hz to 480Hz) and fault read outs, eliminating costly microcontrollers.

Additionally, the iW7011 offers an 85V capability on drain sensing, which means there is no need for cascodes or zener clamps for protection, while high-voltage drain sensing eliminates external diodes usually required for LED short-circuit fault management.

“We believe the iW7011 is the industry’s first truly flexible, scalable and cost-effective backlight solution,” said Athar Zaidi, iWatt’s VP of marketing for DC-DC products. “It reduces the BOM cost and allows one LED driver type to be used across different size LCD panels and for both 2D and 3D TVs, helping customers simplify design with price-competitive products.”

The digital control engine in the iW7011 improves overall system efficiency by optimizing the DC-to-DC voltage based on the minimum feedback voltage of the LED strings that is required to maintain the target current regulation. The digital control engine also generates the current sink PWM waveforms, processes the fault conditions, and reports on all faults.

The iW7011 enables accurate dimming control, with 14-bit resolution at 120Hz PWM frequency. It offers the flexibility of phase-shifted dimming of the current sinks either through direct PWM mode or through an SPI interface.

Additionally, an optional 8-bit analog register can be used to increase the dimming resolution. Phase-shifted dimming reduces capacitance demand on the input and output to improve both dimming linearity and EMI (electromagnetic interference) performance. Four phase-shift dimming options are available: three fixed options for 6-channel operation and an adaptive phase shift option where the shift is evenly distributed based on the number of active channels.

The iW7011 features a wide input voltage of 10V to 28V and LED current up to 300mA. It provides high, 2% channel-to-channel matching accuracy and 0.5% absolute current accuracy to deliver uniform brightness across the entire display. Comprehensive, built-in protection features include over-voltage, over-current, UVLO and over-temperature protection on the boost converter, with open detection and short fault protection for the LED drivers.

The iW7011 is packaged in a 44-pin, 10mm x 10mm, thin QFP with 0.8 mm pitch and a pin-out optimized for single-layer PCB layout.

New LED-downlight reference design from Power Integrations achieves high-performance dimming while reducing component count

USA: Power Integrations has announced RDR-347, an LED-downlight reference design. The new circuit demonstrates the capabilities of the recently launched LYTSwitch IC family, which offers the industry’s best high-end dimming performance from a single-stage LED driver – together with all the associated efficiency, space and cost benefits that the single-stage approach brings.

The RDR-347 12 W reference design, based on the LYT4313E, delivers a power factor greater than 0.95 and reduces total harmonic distortion (THD) to less than 10 percent - easily meeting EN61000-3-2C requirements. Efficiency is greater than 86 percent at 120 VAC – industry-leading performance for an isolated solution capable of operating with a wide range of dimmers.

This performance is possible because LYTSwitch ICs use one combined PFC and CC power conversion stage which minimizes losses and cuts component count, which in turn increases reliability and decreases cost.

TRIAC dimming is challenging, especially deep-dimming where TRIAC asymmetry between half-cycles can have a significant effect. RDR-347 shows that Power Integrations’ LYTSwitch driver IC works excellently, even at very low output currents, without any shimmer or flicker.

The design also demonstrates system start-up without noticeable hysteresis (so-called “pop-on effect”), even in deep-dimming. The IC features a very fast start-up time (under 500 ms) even when dimmed to 10 percent output current, achieving the “instant-on” condition that many customers want, but that many designs in the market cannot provide.

Cree, Nichia, Rohm Semiconductor among top firms in LEDs and power electronics

USA: LEDs are projected to grow more than six-fold to nearly $100 billion and power conversion electronics to $15 billion over the next decade as the desire for energy efficiency drives adoption, says Lux Research.

While the market opportunity is clear, the winning positions are still very much up for grabs, so making wise partnership and investment choices is critical.

“A slew of developers are working on innovative materials and system architectures, targeting the primary challenges of cost reduction and manufacturability,” said Pallavi Madakasira, Lux research analyst and the lead author of the report titled, “Winning the Jump Ball: Sorting Winners from Losers in LEDs and Power Electronics.” “Many leading lights of the electronics industry are strong in these markets, but start-ups with novel technologies are looking to grab a share for themselves.”

Lux Research positioned the key developers of LEDs and power electronics materials, devices, and systems on the Lux Innovation Grid based on their Technical Value and Business Execution – companies that are strong on both axes reach the “Dominant” quadrant. They also assessed each company’s maturity, and provided an overall Lux Take. Among their findings:

* SiC players are dominant in power electronics. The ”Dominant” power electronics players wager mostly on SiC. Cree is a fully vertically integrated SiC device manufacturer, while other top leaders are experienced players from silicon power electronics like Infineon, Rohm Semiconductor and ST Microelectronics.

* Cree, II-VI Wide Bandgap lead materials space. Cree is also “Dominant” in materials, based on its development of SiC substrates. The only other company with a “dominant” rank is II-VI Wide Bandgap Group, an SiC wafer supplier with established relationships with power electronics and RF device manufacturers.

* Six vie for dominance in LED. Cree is the leader in LEDs as well, the only firm that has successfully commercialized SiC-substrate-based LEDs at scale. Among other “Dominant” firms, Nichia holds the most IP, while Samsung, Philips, and Osram Opto Semiconductors have all demonstrated GaN-on-silicon LEDs. GE Lighting does not have its own chip technology but its integration further down the value chain and its recent acquisition of fixture manufacturer Albeo make it a force to reckon with.

The CS18 luminaire will bring an extraordinary combination of performance, aesthetics and optimal light distribution to the sales floor of the Mt. Pleasant Walmart Neighborhood Market.

IXYS integrates thyristor and IGBT in SMPD module platform

SWITZERLAND: IXYS Corp. has released its latest addition to the ISOPLUS surface mount power device (SMPD) range, which successfully reduces the amount of discrete devices for designers that need to apply insulated gate bipolar transistors (IGBT), thyristor and fast diode technologies in one circuit.

The patented SMPD module platform has successfully improved reliability and reduced board size by offering surface mount solutions for systems up to 15kW. Using IXYS’ proprietary DCB isolated substrates the SMPD module flexibility provides a platform for mixed technology and multiple die content, e.g., thyristor, IGBT, MOSFET and diode in boost, buck, parallel, half bridge, full and three phase bridges or two switches side by side topologies.

Dr. Nathan Zommer, CEO of IXYS, said: “Incorporating our thyristors with our IGBT’s has been a natural extension of our depth in power semiconductor technologies. The thyristors have been the highest power density switches for the industry and are relatively easy to drive as high side switches in bridge configuration.

"They conduct higher currents with higher efficiencies than FETs and IGBTs, thus a combination with FETs or IGBTs creates almost an ideal switch, where the high-side-high currents, are conducted by the thyristors, and high speed switching is done with the low side IGBTs in this product. More combinations of these technologies are possible, and will be introduced to our customers' needs as applications power devices (ASPD).”

Integration of the thyristor into a half bridge with an IGBT provides a one-stop solution for power designers needing to operate a low frequency bridge (thyristor) with higher frequency modulation (IGBT). The example of the IXA20PT1200LB is a 20A, 1200V SMPD surface mountable module which contains a thyristor at the high side and IGBT technology on the low side of a half bridge circuit allowing an energy efficient solution for applications such as current source micro-inverter, UPSs, power supplies, motor drives and medical applications.

“This latest release illustrates the true attraction of the SMPD Module platform to our customers,” commented Bradley Green, president of European Sales and Business Development. “Combining any number of our rugged, power efficient die technologies into innovative topologies and packing them in our surface mount, pick-and-place ready module platform for energy sensitive applications is a true differentiator.”

“The SMPD Module is a platform that provides ‘solution-scale’ resolution to power problems by reducing board real estate requirement and component count and weight and power loss due to parasitic inductance. We will continue to develop products which resonate with customers’ demand for MORE POWER - LESS PACKAGE and IXYS fully intends to retain the leading edge in providing innovation in this field,” he continued.

The free-of-charge software is compatible with any laptop or tablet operating with Windows XP SP2 through Windows 7 64 bit. Connection to the PIM Master MW82119A can be made over Ethernet or compact Wi-Fi travel router. The new software continues Anritsu's commitment to providing the marketplace with test solutions that address field market conditions.

The software will work with all six PIM Master MW82119A models, which address key frequency ranges, including the upper and lower 700 MHz bands, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, and 1900/2100 MHz. PIM Master MW82119A analyzers incorporate Anritsu's patented Distance-to-PIM (DTP) technology, allowing tower contractors, maintenance contractors, and wireless service provider field technicians to pinpoint the location of PIM problems, whether they are on the tower or outside the antenna system.

The analyzers also test at 40W, which allows the PIM Master MW82119A to locate faults that conventional 20W test solutions might miss, such as intermittent and power-sensitive PIM problems.

As with all Anritsu handheld test solutions, the PIM Master MW82119A is designed to withstand transportation shock, vibration, and harsh outdoor test conditions associated with cell site deployment, installation, and maintenance. Testing is simplified by the analyzer's ability to save and recall test set ups for standardized testing, and limit lines can be set for visual and/or audible pass/fail criteria.

Anritsu's Line Sweep Tools can be used to manage PIM Master MW82119A measurements, and generate reports that combine VSWR data, as well as PIM data into a unified site report. PIM measurements can be tagged with the GPS location when the analyzers are equipped with the GPS option.

The PIM Master MW82119A remote control software will be available for download from the Anritsu website after March 8, 2013

New LC-XD connector doubles fiber density, improves handling

SWITZERLAND: A ground-breaking new fiber optic connector, launched at the FTTH Council Europe’s conference, will double the density of fibers per rack and improve handling in Central Offices and Data Centres.

Developed by Swiss company, HUBER+SUHNER, a leading international manufacturer of components and systems for electrical and optical connectivity, the new connector significantly reduces the amount of space needed, helping to control costs and improve efficiency.

The LC-XD fiber optic connector, available in both simplex and duplex (Uniboot) versions, handles up to 4032 fibers in one rack, doubling the density handled by previous components. The connector is equipped uniquely with a rigid, extended lever that employs an innovative push/pull mechanism (patent pending), at the same time allowing greater density and more efficient handling.

For both installation and for ongoing handling, vertical space and finger access at the connection are needed, the LC-XD connector, due to its rigid lever, also allows mating and unmating from a distance.

For FTTH applications, with their high fiber density requirements, this will dramatically cut the amount of space required in the Central Office, where space is always an issue. The two most important factors that determine the cost of the passive infrastructure in a Central Office or Data centre are space and handling and focusing on either one of these can lead to increased costs. The key is to achieve a balance between packing density and good handling. With performance continuing to increase, costs per unit are falling and this also puts greater pressure on the issue of the density.

3M launches active optical cable for SFP+ apps

USA: Designers of high-performance computing systems, data centers and other ultra-high-throughput networks have a new interconnect option for SFP+ applications.

3M now offers the low-power, high-speed Active Optical Cable (AOC) Assembly for SFP+ Applications. It is the first known cable assembly of its kind available on the market that is designed for reaches up to 100 meters. The direct-attach, bi-directional AOC assembly supports speeds of more than 10 Gbps per channel over OM 2+ bend-insensitive fiber. It can be used to connect high-performance switches, servers and storage.

The AOC assembly consumes less power than the typical SFP+ interconnect solutions – active copper cable assemblies or active optical pluggable transceivers. The light-engine technology in the 3M AOC assembly allows the cable assembly to operate typically at 240mW per end, helping to save energy costs and minimize heat dissipation. The cable assembly incorporates 850nm VCSEL technology, which has a proven track record of high reliability.

“The 3M architecture for SFP+ applications eliminates the traditional TOSA/ROSA found in pluggable transceivers and allows for direct attachment of the fiber to the light engine,” said Jeff Bullion, marketing manager, Electronic Solutions Division.

“The 3M AOC architecture provides a lower cost solution by eliminating components, lowering the risk of optical contamination and reducing the power required to implement an active SFP+ solution. Now, network designers and installers have a cost-effective, lower-power, highly reliable single solution for lengths up to 100 meters.”

The AOC assembly from 3M eliminates many of the issues associated with other widely used interconnect options. It is lighter and more routable than conventional passive and active copper solutions, allowing more air flow and consuming less space. The optical interface is integrated into the cable assembly, lowering power use and virtually eliminating the risk of optical contamination associated with pluggable transceiver modules.

The SFP+ AOC from 3M is compliant with the SFF-8431 Rev4.1 SFP+ specification and supports the 10GB Ethernet and 4GFC and 8GFC Fibre Channel specifications.

Power efficiency now dominant factor in mobile design

SPAIN:  Imagination Technologies says that power consumption and thermal envelope considerations are becoming a dominant factor in mobile SoC design decisions.

Imagination puts very significant research into design for low power to help extend the ever-essential battery life of mobile and embedded computing systems. Designing first for low power has made Imagination the leading GPU supplier for mobile markets as well as a key supplier in other markets such as thin, flat TVs, complex automotive dashboards, connected audio/media players and ultra-portable computers, where power and thermal constraints can be just as demanding as in mobile devices.

Tony King-Smith, EVP marketing, Imagination, said: "The industry needs a call to action to acknowledge the realities of low power and thermal requirements in end user products running real software, not development boards just running benchmarks. Everyone talks about the importance of power management, and that's an area where the best in the industry have really drawn ahead of the pack by adopting technologies and developing design approaches that support sophisticated power management in SoCs.

"Unfortunately benchmarks used for system performance measurement rarely take account of power use even though this is a key factor in all modern designs. We are working closely with the benchmarking industry to address this in future benchmarks and are encouraging everyone in the industry to take into account power under real end product operating conditions when considering performance metrics."

Cree and Eta Devices to demo world’s most efficient power amplifier

Mobile World Congress 2013, USA: Cree Inc. and Eta Devices Inc. will demonstrate the world’s most efficient reported power amplifier for mobile base stations at the 2013 Mobile World Congress, February 24-28 in Barcelona, Spain.

Current generation mobile base station amplifiers employing silicon LDMOS transistors can provide amplifier efficiencies up to 45 percent. By contrast, Eta Devices’ next-generation power amplifiers are able to deliver efficiencies higher than 70 percent under a 4G LTE modulation format, and are thus poised to revolutionize current industry efficiency standards.

“Eta Devices’ next-generation power amplifiers leverage the performance and reliability advantages of Cree’s GaN HEMT RF transistors to realize game-changing efficiency benefits for the mobile base station industry,” said Jim Milligan, business director, Cree RF. “Our transistors have been instrumental in demonstrating Eta Devices’ amplifiers, which perform 50 percent more efficiently than the best incumbent silicon power amplifiers currently available in the 4G LTE market.”

The world’s mobile networks consume approximately 120TWh of electricity per year, and 50-80 percent of these networks’ power is consumed by their power amplifiers and associated components.

Implementing Eta Devices’ new power amplifier solution on a global level could save mobile operators 60TWh of energy per year, which is equivalent to the amount of power produced by more than seven average-sized American nuclear power plants. It could also save up to 50 percent of the $36.5 billion spent to power mobile base stations each year.

Benefiting from smart phone and TV stocking demand, LED manufacturers gradually increases revenue in January 2013

TAIWAN: According to LEDinside, the LED research division of TrendForce, the total revenue of Taiwanese listed LED manufacturers in January 2013 is 8,220 million NTD (+21.5 percent MoM, +39.9 percent YoY).

LEDinside indicated that in addition to the fourth quarter of 2012 (traditional off season), the TV manufacturers’ delay in stocking will also cause difficulties in the fourth quarter revenue of LED manufacturers. In January, however, LED manufacturers have started to benefit from smartphone and TV stocking demand. In short, LED backlight market is starting to rise, and the revenue of Taiwanese upstream and downstream firms are also increasing impressively.

Followed by commercial lighting stocking demand, LED chip and package manufacturers benefit from the rising backlight market
Due to upstream LED epitaxy manufacturers facing the increasing backlight market stocking demands, the revenue of Taiwanese listed LED chip manufacturers has increased to 3,090 million NTD (+23.7 percent MoM, +32.7 percent YoY).

The revenue of Taiwanese listed LED package manufacturers has also increased to 5,130 million NTD (+20.17 percent MoM, +44.6 percent YoY); not only did the revenue of Lextar Electronics Corp. increase due to the merging with Wellypower Optronics Corp., package manufacturers’ capacities was were also boosted by the increasing market demands.

Due to the launching of Samsung’s new direct-type LED TV models in the second quarter of 2013, a stocking effect appeared in the first quarter; compared with the same quarter in 2012, Taiwanese manufacturers have extricated themselves from the economic slowdown and started to increase their revenue. Benefiting from Korean manufacturers’s OEM order, Epistar Corp. and Formosa Epitaxy Incorporation Inc. significantly increased their revenue; it is expected that the order visibility continue till extends to the end of the first season.
Moreover, due to the fact that the quality of chips manufactured by Taiwanese manufacturers are better than that of Chinese manufacturers, the increasing shipments of Chinese TV vendors such as Skyworth, Hisense, TCL, Konka, and Changhong Electronic Corp. may be an opportunity for Taiwanese chip manufacturers to enter the Chinese TV backlight supply chain.

The stocking demand for another backlight demanding market- smartphones is also increasing. Not only improve was backlight brightness improved, but also raise shipment forecast was also raised by 28 percent in 2013. Amongst those, apart from international brand manufacturers, Chinese manufacturers also took advantage of this trend and started to rise, becoming potential clients of Taiwanese LED manufacturers.
Generally speaking, both chip and packaging manufacturers with a certain proportion of revenue that comes from the smart phone and TV supply chain have achieved significant increase in their revenue. Extricating from the gloomy year of 2012, chip revenue was boosted up to 1,350 million NTD; in addition, Formosa Epitaxy Inc. and Genesis Photonics Inc. have also achieved 300 million NTD and 270 million NTD respectively.
As for the lighting market, the second season is the traditional peak season of commercial lighting. Facing the challenge of intra-industry competition, LED package manufacturers are planning to release new products, and we expect the LED package to fall mainly between 160lm/W~180lm/W at the mass production level.
LEDinside also indicated that considering about the broad LED product applications including commercial and outdoor lighting along with the technical advantages of Taiwanese manufacturers, the future integrating focus of the LED industry will possibly include joint projects performed by Taiwanese LED chip manufactures, package manufacturers, and Chinese lighting manufacturers. Under the integrating and marketing adjustments, second-tier manufacturers will be facing another market challenge.

Cree sets new R&D performance record with 276 lumen-per-watt power LED

USA: Cree Inc. has delivered another industry first with a barrier-breaking 276 lumen-per-watt white R&D power LED. This significant milestone exceeds Cree’s previous R&D industry record of 254 lumens per watt and demonstrates Cree’s continued commitment to innovate and accelerate the adoption of LED lighting.

Cree’s innovative SC³ Technology platform, available in Cree XLamp LEDs, enables this record-breaking R&D result. The SC³ Technology Platform features advancements in LED chip architecture and phosphor and boasts a new package design to deliver the most advanced LED components in the industry.

Cree reports that the LED efficacy was measured at 276 lumens per watt, at a correlated color temperature of 4401 K and 350 mA.

“The core of the Cree R&D culture is a relentless focus on innovation that ultimately drives LED adoption,” said John Edmond, Cree co-founder and director of advanced optoelectronics. “The innovation from our labs is the foundation for our lighting-class XLamp LEDs. Higher performance LEDs can enable new and better LED-based applications and drive down the solution cost of LED designs.”

iWatt Flickerless SSL LED driver optimized for commercial and wireless lighting

Strategies in Light Conference, USA: iWatt Inc., a leading provider of digital-centric power management integrated circuits (ICs), debuted an innovative digital AC/DC LED driver platform designed to address cost, performance and operating life in commercial and wireless solid state lighting (SSL) systems.

The first device in this new platform, the iW3630 is a two-stage, Flickerless LED driver with output power up to 45W and is believed to be the first SSL LED driver with a built-in 0V to 10V dimming interface for commercial lighting ballasts. It also supports a PWM digital dimming interface for wireless SSL applications.

The highly integrated design of the iW3630 enables a 30-40 percent savings in bill of materials (BOM) cost compared to competitive solutions in 0V to 10V applications and, unlike alternative solutions, it maintains an extremely high power factor (PF) even at loads down to 20 percent of full load.

It also offers a low total harmonic distortion (THD) of < 15 percent, to meet stringent global energy regulations, along with a built-in over-temperature protection (OTP) and derating function to improve the predictability and reliability of system operating life.

The iW3630 achieves a 30-40 percent savings in BOM cost by integrating a number of design features. A built-in isolation transformer driver works directly with 0V to 10V dimming systems, eliminating the need for additional driver circuitry components and costly microcontrollers, while the PWM digital interface simplifies integration into wireless lighting systems.

In both commercial and wireless applications, the built-in over-temperature protection and derating function means there is no need for additional components to control heat. Plus, iWatt’s patented PrimAccurate primary-side control technology eliminates the need for a secondary-side regulator and optical feedback isolator, while EZ-EMI technology simplifies EMI filtering to further minimize the external component count.

This combination of on-board functions results in a typical BOM of less than 70 components using the iW3630 compared to often more than 100 components needed using conventional SSL LED drivers. It also reduces the overall solution size and improves reliability.

“We already offer the broadest range of SSL LED drivers in the market,” said Hubie Notohamiprodjo, iWatt’s director of marketing for SSL products. “The iW3630 further expands our reach with our first, and the industry’s first dedicated driver for commercial dimming applications.”

The digital control architecture of the iW3630 simplifies ballast driver designs by allowing it to adapt to wide input and output conditions. This enables one configuration to support a wide range of LED string lengths to cover the full output power range. iWatt’s analysis of one example lighting ballast portfolio using the iW3630 resulted in the ability to replace nine existing ballasts with just three, thus reducing the number of production models needed.

The iW3630 uses iWatt’s Flickerless technology to eliminate flicker across the entire 1 percent to 100 percent dimming range, while providing tight, ±5% LED current regulation. Flickerless technology incorporates a power factor correction (PFC) circuit comprised of a chopping circuit. This circuit ensures high power factor and also virtually eliminates the input line-voltage frequency component.

The on-chip over-temperature protection and derating feature of the iW3630 monitors the temperature inside the ballast. When thermal conditions reach a point set by the system designer, the iW3630 LED driver automatically reduces the current drive to the LEDs, lowering the power dissipation and resulting in cooler overall operation. This avoids the risk of thermal runaway, ensures the temperature rating of the electrolytic capacitors in the lighting system is not exceeded, and allows a predictable operating life. Additional built-in protection features include LED open/short, input over-voltage, over-current, and current-sense resistor short protections.

The iW3630 is available now in production quantities. It comes in a standard, 14-lead SOIC package. Samples are available at $1.16 in 1,000-piece quantities.

States patent number 8,305,013 for its Circuits and Methods for LED Free Dimming control; a continuation of the invention issued February 2012 under United States patent number 8,111,017.

Free Dimming is O2Micro's dimming technology built into a LED light source. It allows the end-user to toggle dimming control using any standard on/off wall switch.

"This patented technology enables dimming control in LED lighting using an ON/OFF wall switch. The technology saves the cost of installation and compatibility issues associated with traditional incandescent dimmers," said Dr. Yung Lin, executive VP at O2Micro.

Philips unveils LUXEON S emitters

USA: Philips Lumileds introduced LUXEON S, its second generation illumination-grade multichip emitters which offer twice the lumen density of existing solutions, an R9 value that exceeds 80 and has 50 percent better Color over Angle (COA) variation over existing solutions.

Philips Lumileds is demonstrating the new LUXEON S emitters this week at Strategies in Light, February 12-14 in Santa Clara, California (Booth #205).

Designed for retail, architectural and entertainment applications, LUXEON S emitters deliver up to 50 lumens per square millimeter and a high light output of up to 8000 lumens in narrow beams with sharp shadows.

Because of the challenges in creating a small footprint with tight beam angles and high lumen density, luminaire designers have had to deal with large optics and limited lumen levels.  With LUXEON S, luminaire designers have more flexibility and can achieve beam angles in the 8 degree range in a compact design, with light levels that rival traditional CDM light sources.

This flexibility enables never-before-possible Center Beam Candle Power (CBCP) of over 50,000 candela, compared to other LEDs, like Chip on Board (COB) solutions, with a larger Light-Emitting Surface (LES) that achieve less than 20,000-25,000 candela.

"With a lumen density that is twice that of available solutions, the LUXEON S can offer light outputs as high as 8000 lumens at half of the optical size, enabling LED approaches to replace traditional ceramic discharge metal-halide (CDM) lamps in spotlight and architectural applications," said Orson Lo, director of LUXEON S products for Philips Lumileds.

"Relative to CDM lamps, LUXEON S-based lamps offer comparable efficacy of 90 lm/W but with instant-on operation, better color consistency and four times the expected lifetime at 60,000 hours."

The new emitters feature correlated color temperatures of 2700K and 3000K with a CRI of 80 or 90, as well as CCTs of 3500K, 4000K and 5000K at CRI of 80.  In the 90 CRI products, R9 value exceeds 80, making them ideal for applications requiring exceptional color renderings such as in premium retail and museum applications.

450W TVS diode arrays from Littelfuse protect sensitive electronics from ESD and surge currents

USA: Littelfuse Inc. has introduced the 450W SD05 (unidirectional) and SD05C (bidirectional) series general-purpose TVS diode arrays (SPA devices), which are designed to replace multilayer varistors (MLVs) for protecting electronic equipment from damage due to electrostatic discharge (ESD) and other transient events.

Unlike ceramic devices, which have an inherent wear-out factor, SD05 and SD05C Series devices are made of silicon diodes, which allows them to absorb repetitive ESD strikes or surge transients safely without performance degradation.

Their low dynamic resistance (0.5Ω for SD05, 0.6Ω for SD05C) provides up to a 50 percent reduction in clamping voltage when compared with competing technologies, and can safely dissipate induced surge currents up to 30A.

Typical applications of these devices include buttons/keypads, switches, DC power ports, and various other low-speed I/Os in point-of-sale terminals, test equipment or instrumentation, medical equipment, desktop/notebook computers, servers, computer peripherals, etc.

“The SD05 and SD05C Series are perfect solutions for medical, industrial, consumer and computing applications. They allow designers to add ESD and/or surge protection around the printed circuit board (PCB) as needed,” said Chad Marak, director of the Littelfuse TVS Diode Arrays product line.

“Their compact SOD-323 package fits right into the footprint of an 0805 MLV, allowing manufacturers to replace them in their designs with a SD05 or SD05C device without requiring a PCB or solder pad change.”

TI's new LED drivers simplify retrofit light bulb design

USA: Texas Instruments Inc. (TI) introduced the industry's smallest off-line, phase-dimmable, constant-current lighting controller and an easy-to-use lighting driver that simplify the retrofit of a variety of LED bulbs, including E14, GU10, A19, PAR20/30/38, MR16 and AR111.

The TPS92075 controller and TPS92560 driver reduce component count and solution size while improving compatibility with legacy lighting controls.

The TPS92075 is designed for phase-dimmable, offline AC/DC LED lamp and downlight applications.  Offered in a very small 6-pin TSOT package, it achieves power factor correction above 0.9 while delivering smooth, flicker-free dimming when used with conventional wall dimmers.

The TPS92560 is intended for use in low-voltage AC or low-voltage DC LED lamp applications such as MR16 and AR111. It uses a proprietary input current control method, which improves compatibility with electronic transformers.

The TPS92075 and TPS92560 join TI's LED driver portfolio for retrofit bulbs that includes the LM3445, LM3447, TPS92310/11/14, LM3444 and LM3401.

ISSI intros TRIAC dimmable LED driver IC for retrofit light bulbs

USA: Integrated Silicon Solution Inc. has announced the first member of the Flicker-Free family of devices, the IS31LT3935.

This is ISSI's latest solid state lighting (SSL) LED controller featuring a dimming core based on patent pending AccuDim technology. AccuDim is an advanced proprietary technique that mimics the characteristics of an incandescent light bulb for true dimming performance with all dimmers maintaining a high power factor.

In addition to offering near 100 percent compatibility with leading edge, trailing edge and digital TRIAC dimmers, designs employing the Flicker-Free IS31LT3935 will realize a substantial savings in bill of materials (BOM) cost due to the low component count.

The IS31LT3935 is a current mode LED controller that enables the 120V/230V AC lamp applications with a high power factor, high efficiency and a low component cost in a small PCB area. Designs using this single stage controller will experience a near unity power factor just like an incandescent lamp yet with very high efficiencies (up to 87 percent).

Other device features include spread-spectrum switching for reduced EMI, safety features such as input over-voltage protection, over-temperature thermal shutdown (with hysteresis) and AC line under voltage lockout. The controller IC feature set enables system designers to exceed all EMI and regulatory standards worldwide.

The IS31LT3935 can be configured as a high-frequency buck mode converter or as a primary side sensing flyback converter. Either mode of operation enables a solution that is both compact and cost effective. Though IS31LT3935 operates over a universal input voltage range (85V to 265V), Flicker-Free reference designs can optimize solutions that are highly efficient and have the lowest BOM by targeting a specific range such as 100V-120V or 220V to 240V AC input voltages up to a 25W power level. Such optimization enables customers to achieve lower overall cost with best in class performance in the smallest form factor to accommodate bulb retrofit designs.

The IS31LT3935 is sampling now and will be available in production quantities in Q2 2013. It is available in a small 3x3mm DFN-10 package with exposed pad and is priced at $0.89 in 1,000 piece quantities.

KEMET further expands C0G and X8R flexible termination portfolio

USA: KEMET Corp., a leading manufacturer of tantalum, ceramic, aluminum, film, paper and electrolytic capacitors, announced the expansion of its Flexible Termination (FT-CAP) product portfolio in C0G and Ultra-Stable X8R dielectrics. KEMET has extended case size offerings as well as capacitance values in both dielectric platforms.

"KEMET's C0G-type multilayer ceramic capacitors offer industry-leading performance and exceptional capacitance stability up to 125 degrees C," stated Dr. Abhijit Gurav, KEMET VP, Ceramic Technology. "Combined with superior flex performance, Ultra-Stable X8R devices are ideal for use at high temperatures up to 150 degrees C in higher reliability applications such as down-hole drilling and engine compartments."

C0G and Ultra-Stable X8R capacitors with flexible termination outperform devices with standard termination systems and are well suited for critical and safety relevant circuits without (integrated) current limitation, as well as any application that is subject to high levels of board flexure or temperature cycling.

These devices are RoHS compliant and available with an optional tin-lead finish. In addition to Commercial Grade, Automotive Grade (AEC-Q200) devices are available for mission and safety critical circuits requiring stricter testing protocol and inspection criteria.

Flexible termination technology was developed in order to address flex cracks, the primary industry failure mode of surface mount MLCCs. This technology directs circuit board stress away from the ceramic body and into the termination area, thereby reducing the risk of mechanical damage to the component that can result in low IR or short circuit failures.

FT-CAP complements KEMET's Open Mode, Floating Electrode (FE-CAP), Floating Electrode with Flexible Termination (FF-CAP), and KEMET Power Solutions (KPS) product lines by providing a complete portfolio of flex mitigation solutions.

Super junction MOSFET business update.

USA: announced that a new market research report is available in its catalogue: Super Junction MOSFET Business Update.

It's no secret: Consumer is SJ MOSFET's main application segment, representing 2/3 of its total market. While some applications are stagnant, i.e., desktop PC and game console power supplies, most applications are still growing.

The biggest growth area will be power supplies for tablets, with an expected 32 percent increase in CAGR from 2013 to 2018. However, the main products where SJ MOSFETs are used are PC (desktop and laptop) power supplies and TV sets, which total half of the SJ MOSFET market as presented in this report.

The driver for using SJ MOSFET in these applications is, first and foremost, size reduction. SJ MOSFET allows for a much smaller size than planar MOSFET, since they generate less heat.

The Hybrid and Electric car markets should not be ignored. True, they are less than $5 million today, but they will represent more than $100 million by 2018.

This report clarifies the situation of SJ MOSFET in EV/HEV markets, and shows how SJ MOSFET will be used in DC/DC converters and chargers and how it provides accurate market metrics.

Industrial applications are less interested in SJ MOSFET use, since these applications do not require a high frequency of switching when operating in an H-bridge. SJ MOSFET is interesting only for specific topologies such as multi-level, or for cheap, low-power solutions (small UPS, residential PV) - but even in these applications, planar MOSFET or IGBTs remain better solutions since they are cheaper and meet all requirements.

The technology used for Super Junction MOSFET is of two types. The first one, developed by Infineon, uses a series of epitaxies and doping to create a locally doped "island" in the epi-layer. The doped region then diffuses and creates an N-doped pillar. The second technology uses deep reactive ion etching to dig a trench. This trench is then filled with an N-doped material to create the super junction structure. Players exploiting this particular technology are Toshiba, Fairchild Semiconductor and IceMOS Technology.

Technology evolution is accelerating and the opposition between multiple epitaxy and deep trench is growing stronger. Toshiba released its 4th generation of its DTMOS, a deep trench power MOSFET with a smaller pitch size. It means a smaller die size and an improved RdsON. It's still more expensive to produce than a CoolMOS (Infineon's brand name), but it's becoming more and more competitive.

Compound semiconductor remains a threat to SJ MOSFET. SiC will be positioned at higher voltage and will target high-end solutions as well. Silicon will still be present in 2015. IGBT is the best cost vs. switching efficiency trade-off, and International Rectifier is working on high-speed IGBTs that are competing directly with Super Junction MOSFET. In the end, SJ MOSFET is positioned in-between, and depending on the voltage, application and frequency of switching, it could compete with SiC, Fast IGBT, IGBT or GaN.

This report also presents evolutions in packaging, which has become a part of the game. In 2010, STMicroelectronics and Infineon maintained their leadership role by providing a common package type of very small size. It fits perfectly with consumer applications, where size reduction is a strong driver.

Agilent announces industry’s highest-performance real-time spectrum analyzers

USA: Agilent Technologies Inc. announced the availability of real-time spectrum analysis (RTSA) for its PXA X-Series signal analyzers. Agilent’s RTSA delivers unmatched probability of intercept (POI), analysis bandwidth, sensitivity, and frequency range—capabilities that make it the best way for system developers and signal analysts to see, capture and understand highly elusive signals.

In applications such as radar, electronic warfare and military communications, POI is the key benchmark for RTSA. When configured for real-time spectrum analysis, the PXA can detect intermittent signals with durations as short as 3.57 µs, which is the best POI currently available.

“Even at the extremes of signal analysis, a high-performance analyzer should be ready for anything—and that’s why RTSA is an upgrade option to the PXA,” said Guy Séné, president of Agilent’s Electronic Measurement Group. “Only the real-time PXA combines a high-performance signal analyzer and real-time analysis. It gives users greater confidence that they’ve achieved a detailed understanding of what’s happening inside a signal-rich system or environment.”

To help detect more signals in less time, Agilent’s real-time PXA provides an industry-leading 75-dB spurious-free dynamic range across analysis bandwidths of up to 160 MHz. This enables users to place deep and wide measurements anywhere within a measurement range of 50 GHz.

In addition to its industry-leading sensitivity of -157 dBm at 10 GHz (no preamp), the PXA also provides the ability to vary the resolution bandwidth within a measurement span. With this combination of capabilities, users are better able to resolve closely spaced signals, identify intermittent low-level signals and further improve POI.
