Diodes Inc. versatile LED driver increases reliability of HB lamp systems

DALLAS, USA: Diodes Inc. has announced a multi-topology LED driver IC designed to increase the reliability of high brightness lamps in automotive, industrial, and commercial lighting systems.

The ZXLD1370 LED driver controller operates in buck, boost, and buck-boost modes. It combines patent pending control loops and high-side current sensing to ensure accurate current control of LED strings.

With an extended 6V to 60V operating input voltage range and a typical 1 percent output current tolerance in all topologies, the driver is capable of delivering the high current levels and tight inter-lamp luminance-matching required by high brightness LED systems.

LED reliability and longevity is improved by active LED thermal management achieved via a dedicated external thermistor input, and by fault diagnosis outputs that report the status of LED driver and load.

The ZXLD1370 LED driver controller, used with an external MOSFET, provides a single driver solution capable of supporting a very wide range of LED configurations and current requirements. It supports high accuracy dimming through DC dimming and PWM dimming options.

With a dedicated PWM input, the driver offers a 1000:1 dynamic dimming range at 1 kHz. This allows for high accuracy control of color mixing and excellent resolution at low brightness levels.

The device’s 1 MHz switching frequency capability with 100 kHz low frequency clamp also means a reduction in the size of the external inductor and simpler design of input EMI filters should they be required.

LCDs face LED backlight supply shortage as shipments more than double in 2010

EL SEGUNDO, USA: Amid soaring demand from televisions, mobile computers and desktop monitors, LEDs used for backlights in large-sized LCDs are suffering a tight supply situation that will last until the near the end of 2010, according to iSuppli Corp.

Shipments of large-sized LCD panels with LED backlights are forecasted to reach 276.7 million units in 2010, up a dramatic 134.9 percent from 117.8 million in 2009. In 2010, LED backlights will be used in 43.1 percent of all large-sized LCD panels, which mainly are used in LCD-TVs, mobile computers and desktop monitors. LED backlights are also starting to see increasing use in electronic signage, industrial and medical applications.

LED backlight shipments will rise to 477.6 million units in 2011 and continue to expand to 817.9 million units in 2014. By then, LED backlights will have penetrated 87.7 percent of the total large-sized LCD market.

Usage of LED backlighting is soaring due to its substantial advantages compared to the older Cold Cathode Fluorescent Lamp (CCFL) technology, including slimmer design, reduced weight lower power consumption and mercury-free attributes for a greener, more environmentally friendly solution.

The figure presents iSuppli’s worldwide forecast of unit shipments of large-sized LCD panels with LED backlighting systems. iSuppli defines large-sized LCD panels as those having a diagonal dimension of 10 inches or more.Source: iSuppli, USA.

This rapid rise in shipments has spurred supply constraints for LED backlights.

“There have been mounting concerns in the industry about supply constraints for LEDs and light guide plates, two of the major components for LED backlights,” said Sweta Dash, senior director for LCD research at iSuppli. “Changes in light guide design, constraints in raw materials and high expansion costs are limiting capacity.”

The other major constraint, Dash said, revolves around the challenges faced by Metal Oxide Chemical Vapor Deposition (MOCVD) reactors—the key equipment for making LED chips—to keep up with demand. As a result, tight supply of LED chips is expected until the end of the year.

LED supply inequality
The LED shortage is not expected to affect all panel makers equally.

“By the second half of this year, a clear distinction will emerge between the ‘haves’ and ‘have-nots’, among the panel suppliers” Dash predicted. “Those panel makers that have their own internal manufacturing of LEDs will have sufficient supply in 2010, while those that don’t will encounter constraints.”

For example, South Korean LCD panel manufacturer Samsung has established Samsung LED, which provides an internal source for LEDs for the company’s manufacturing of LCD panels.

Pump full of LED
To address the availability constraints, LED suppliers are shifting production to 4-inch and 6-inch wafers and away from older 2-inch wafers. This will cause production capacity of LEDs to rise. However, LED makers will need as long as one year to adjust to the change in production technology.

Meanwhile, panel suppliers are expected to offer newer backlight designs that require fewer LEDs per panel. Most panel suppliers expect the number of LED chips per television panel to decline by 30 percent or more at the end of 2010 compared to one year earlier.

LCD panel suppliers also are set to become more vertically integrated in order to better control the LED backlight supply chain. Furthermore, branded TV manufacturers will be partnering with module manufacturers to gain their own backlight solutions and to achieve product differentiation.

“By the end of 2010, the supply situation will improve as capacity rises and new backlight designs require fewer LEDs per panel,” Dash said.

LED rises
The adoption of LED backlights in LCD-TVs will rise to 18.4 percent in 2010, up from 3 percent in 2009, spurred by the push among various TV brands to introduce LED-based TVs. Adoption rates also will climb for notebook panels, rising to 88 percent this year, up from 62.6 percent in 2009. By 2012, LED backlights will be used by 100 percent of notebook panels.

The adoption rate for LED backlights for desktop PC monitors in 2010 will rise to 20.8 percent, up from 1.7 percent in 2009.

LED market explosion hampered by materials shortage

MILTON KEYNES, UK: The fast-growing market for high-brightness LEDs in LCD TVs will be restricted by a shortage of key semiconductor materials in the second half of 2010, as predicted by Strategy Analytics, in its report, “Materials Shortage to Restrict Rampant LED Market.”

Demand for TMG already exceeds the available supply; thus manufacturers need to absorb a 20 percent price increase in the near term. A shortage of sapphire wafers upon which most blue and white LEDs are produced is also likely in the second half of 2010.

This report outlines the challenges facing LED manufacturers in 2010, as the supply constraints and increasing material prices serve to restrict the rapid market expansion.

“Concerns have previously been raised over the ability of MOCVD equipment vendors to meet rapidly increasing demand,” noted Asif Anwar, director of the GaAs and Compound Semiconductor Service at Strategy Analytics. “The concern for short supply of materials will create a bottleneck for LED market growth over the short term.”

Taiwanese LED manufacturers in particular need to adjust to the new reality of the supply chain. Historically, they have bargained for the price of these key materials. But the balance of power in the LED industry has changed, with competitors backed by huge corporations, such as Samsung and LG, much better positioned to absorb higher material costs and to guarantee their supply in a constrained market.

Steven Entwistle, VP of the Strategy Analytics Strategic Technologies Practice, added: “Capacity expansions already in progress should relieve these constraints by mid-2011. Until then, the average selling price of high-brightness LEDs based on gallium nitride should hold up well.”

The IC outputs also feature reverse current protection.

The API9221 features a bypass LDO regulator, enabling a host controller to detect the connection of an out-of-specification supply voltage and safely keep the charger in its off-state condition until a valid supply is connected. The device offers excellent thermal regulation and protection, with the ability to reduce charge current to keep the die temperature within safe operating conditions.

The API9221 follows the industry-standard CC/CV charging algorithm, and enables USB and adaptor charge currents and end-of-charge currents to be user-configured via external resistor settings. With only a 1% error across the device’s operating temperature range, the IC ensures battery charging up to 4.2V.

LED lighting penetration to reach 46 percent of commercial building lamp market by 2020

USA: Lighting accounts for about 17.5 percent of global electricity use and, within the United States, the majority of lighting energy is consumed in commercial buildings.

Recent innovations in lighting technologies, particularly the development of solid state lighting using light emitting diodes (LEDs), hold significant long-term potential for energy savings in the commercial building sector.

According to a new report from Pike Research, LED lighting will become an increasingly important segment of the market, and by 2020 it will achieve a 46 percent penetration of the $4.4 billion US market for lamps in the commercial, industrial, and outdoor stationary sectors.

“LED lighting will reach an inflection point in the next five years,” says managing director Clint Wheelock. “As solid state lighting costs come down and performance increases, LEDs will become a practical option for an increasing number of commercial applications.”

Wheelock adds that LEDs are already widely used in traffic signals and exit sign lighting, and Pike Research anticipates that those markets will become saturated within the next few years. The outdoor stationary sector will be the next growth area for LED lighting, followed by retail and office/professional and institutional buildings.

However, despite the strong long-term prospects for LED lighting, Pike Research’s analysis indicates that the category still faces a number of technological and economic hurdles. As a result, while the cost and efficacy of solid state lighting are rapidly improving, it will be a number of years before LEDs lead the commercial lighting market.

During this period of transition, fluorescent T8 and T5 lamps, which offer good efficacy and life at very reasonable prices, will overtake incandescent lamps as the leading technology prior to the coming of age for LED lighting products.

LED market explosion hampered by materials shortage

BOSTON, USA: The fast-growing market for high-brightness LEDs in LCD TVs will be restricted by a shortage of key semiconductor materials in the second half of 2010, as predicted by Strategy Analytics, in its report, “Materials Shortage to Restrict Rampant LED Market.”

The rapid penetration of LED backlighting modules in LCD TVs has already seen demand soar, for capital equipment, particularly for the metal-organic chemical vapor deposition (MOCVD) reactors used to make gallium nitride (GaN) LEDs. A similar trend is now evident in the supply of consumables, specifically the metal-organic material trimethylgallium (TMG) and sapphire wafers.

Demand for TMG already exceeds the available supply; thus manufacturers need to absorb a 20 percent price increase in the near term. A shortage of sapphire wafers - upon which most blue and white LEDs are produced - is also likely in the second half of 2010.

This report outlines the challenges facing LED manufacturers in 2010, as supply constraints and increasing material prices serve to restrict the rapid market expansion.

“Concerns have previously been raised over the ability of MOCVD equipment vendors to meet rapidly increasing demand,” noted Asif Anwar, director of the GaAs and Compound Semiconductor Service at Strategy Analytics. “The concern for short supply of materials will create a bottleneck for LED market growth over the short term.”

The device is capable of driving up to 36 HB LEDs at up to 100mA per channel. The SC446 operates across a wide input voltage range of 4.5V to 27V, making it ideal for use with automotive batteries or regulated 5V, 12V or 24V power supplies.

The SC446 expands Semtech’s popular HB LED driver platform for mid-size LCD panels in indoor/outdoor displays for automotive, industrial, white goods, avionics, medical and gaming equipment – applications where the high reliability, shock resistance and mercury-free benefits of LEDs are displacing traditional fluorescent (CCFL) bulbs.

These types of rugged LCD panels require an ultra-bright light source for viewing in direct sunlight. The extra design tolerance of the SC446 meets the demands of time and temperature.

The SC446 provides exceptional LCD illumination with up to 100mA per-channel. It also features a rugged, 16-pin thermally enhanced TSSOP package for low operating temperature and long life at high ambient conditions. Additionally, 1mm pin spacing minimizes the risk of pin-to-pin faults arising from PCB contamination in harsh environments.

“The transition from CCFL to LED backlights gives LCD panel manufacturers and systems integrators a simple, cost-effective option for improving the temperature profile and shock ruggedness of their designs,” said Steve Hawley, Semtech Product Marketing Manager for LED Lighting and Displays. “The SC446 offers a driver solution that matches the reliability of the high brightness LEDs themselves.”

The SC446 has a low–loss internal boost switch to provide efficiency of greater than 92 percent. Up to 50kHz PWM dimming eliminates audio noise problems. The optimum LED output voltage is maintained dynamically by the internal DC-DC current mode controller.

Channels can be paralleled for applications requiring low component stress and minimum temperature rise. Channels can also be independently disabled to fit smaller panel designs. The controller switching frequency is optimized at 700kHz for minimum external L/C filter size and highest operating efficiency.

Additionally, the SC446 provides a smooth transition from boost to bypass operating mode, when the input voltage is greater than the output voltage. Current sinks are rated up to 40V. The controller is compatible with the SEPIC converter topology, where the input voltage is greater than, or less than, the output voltage.

The SC446 LED driver has an exposed thermal paddle for optimum heat sinking. The SC446 is Pb-free, halogen-free and fully RoHS compliant.

Lithium battery industry has huge potential for future growth

BEIJING, CHINA:, one of China's leading B2B search platforms, predicts the lithium battery industry has huge potential for growth in the future.

Frbiz's industry analyst said that the lithium battery industry, which has the largest market share in the small rechargeable batteries market, has developed rapidly in recent years; it has become the most widespread form of chemical batteries.

Relative to lead-acid batteries, nickel cadmium batteries, nickel metal hydride batteries and other secondary batteries, lithium batteries have a higher energy density and a longer cycle life, their self-discharge rate is smaller, and they are more environmentally friendly. Lithium batteries have become more widely used as technology advances have lead to more portable electronic products, new energy transport and storage, among other innovations.

Lithium batteries are widely used in portable electronic products such as laptops, mobile phones, digital cameras and digital video cameras. Among them, laptops and cell phones use them the most often. Since 2008, the financial crisis has had an impact on the global consumer electronics market. But with the national policy of graduated economic stimulus, laptops, mobile phones and other portable electronic products' sales have maintained a good momentum.

Meanwhile, with 3G next generation Internet and other new information technology trends, the portable electronic products market will maintain long-term prosperity. For example, in the Chinese market, 3G mobile phone production and sales growth is fast, with total annual sales of 6,637 million sets, up 90% year-on-year.

Recently, Apple introduced the iPad, which immediately set off a new boom in the global information and electronics industry. Products such as these create a demand for lithium batteries, to improve security, performance and cycle performance. This will also lead to an increase in demand for cathode material for high-capacity lithium batteries. Lithium batteries can also be used in electric vehicles.

With the global oil shortage and the deterioration of climate and the environment, as well as other challenges facing the world regarding energy conservation and developing new energy-saving measures and reducing waste emissions, batteries will become more and more important.

Lithium batteries field have important applications in the field of energy conservation; first, they can solve network electricity problems. Second, wind energy, solar energy, and tidal energy are intermittent energy sources, while a lithium energy storage device uses clean energy and can release it steadily, which can effectively alleviate shortages of energy.

Keithley's reed relay matrix card combines ultra-high density and superior configuration flexibility

CLEVELAND, USA: Keithley Instruments Inc. has introduced the model 3732 Quad 4x28 Ultra-High Density Reed Relay Matrix Card.

The card, which offers 448 single-pole matrix crosspoints, was designed for automated switch and measure applications that require multiple instrument connections as well as high crosspoint density and high speed.

It is an ideal solution for use in a wide range of high pin count research and development and production tests applications, such as low-level contact resistance testing of high-speed memory interface boards or next generation IC sockets.

Flexible, highly configurable matrix
Matrix switching configurations offer system designers wide testing flexibility by allowing them to connect multiple inputs to multiple outputs; matrices are particularly useful for applications in which the system must make connections between several instruments and a multipin device.

The model 3732 has four banks of high-speed reed relays; each bank has four rows and 28 columns (4x28), providing a total of 448 single-pole crosspoints. These relays can be configured in a number of different ways, enabling the matrix size to be easily adapted to existing or future applications.

For example, bank-configuration relays included on the card allow configuring the matrix banks automatically as a single 4x112 matrix or as two isolated 4x56 matrices, with no need for external wiring. The card also has analog backplane relays that allow expanding columns across cards automatically, up to a maximum of 4 rows by 672 columns in a single mainframe using six Model 3732 matrix cards.

The model 3732 also supports two-pole switching by automatically pairing relays to create either a dual 4x28 or a single 4x56 configuration.

The card uses dry reed relays that offer both low contact potential and low current offset to minimize the switching errors that often accompany this relay technology. Additionally, these relays will switch up to 200V at carry currents up to 1.2A, specifications not available in other high-density, card-based matrix solutions.

The fast-switching, long-life reed relays have a switching speed of 0.6 milliseconds and are rated for more than 109 no-load operations, both necessary specifications for switching systems used in automated testing applications.

Luminus Devices, Almeco Group demo world’s first single-source LED street light

LAS VEGAS, USA: Luminus Devices, Inc., designer, developer and manufacturer of high light output PhlatLight LEDs, announced a partnership with Almeco Group to demonstrate the world’s first, single-source LED street light.

The new street light is powered by a single CSM-360 PhlatLight LED in combination with Almeco’s novel reflector optic. The result is an aesthetically appealing single-source LED fixture that looks more like an HID-based street light than the typical pixelated LED fixtures that dominate the current landscape.

With an emitting area 36 times greater than a 1-watt LED, a single PhlatLight CSM-360 LED can reduce design complexity, reduce cost and increase fixture reliability. Instead of using arrays of LEDs and optics, the single-source street fixture requires only a single optic. Additional cost savings can be realized from the fact that the CSM-360 is a chip-on-board LED, which doesn’t require an expensive metal core PCB typically used with LED arrays.

Almeco’s breakthrough low glare Vega LED98 reflector design incorporating material with the highest values of reflectivity across the visible wavelength spectrum can take the light from the CSM-360 and distribute it onto the street in accordance with industry standards. With a reflectivity of greater than 98 percent, the LED98 reflector optimizes the overall fixture efficiency.

Seoul Semiconductor launches new LED products at Lightfair

LAS VEGAS, USA: Seoul Semiconductor, a leading global LED manufacturer that recently achieved a noteworthy industry milestone with the development of a new lamp capable of 150 lm/w, is launching several innovative products at Lightfair International, the largest lighting fair in North America, taking place at the Las Vegas Convention Center this week.

Company representatives will be at Booth 1539 in the Las Vegas Convention Center May 12-15 to launch Acriche A6 (1 W) and A7 (4 W) series products, LEDs that are much smaller than existing Acriche lamps and can be used in a variety of general lighting fixtures, including streetlights. For example, the A7, at 8x8 mm, offers space-saving versatility over current 18x12 mm Acriche products.

Acriche is the first mass production AC-driven LED and because it does not require a converter it is less expensive to manufacture end-products and lasts longer than other LED light sources whose lifetime may be limited by a power converter.

Also launching at Lightfair are three next-generation products in Acriche’s Z-Power LED series:
* Z5, which offers a high color rending index (CRI 90) and compact ceramic design;
* Z6, which delivers full color options for general lighting applications as well as decorative and architectural lighting uses;
* Z7, a high-efficiency LED product containing four individually addressable high power die.

“The global market for LEDs now exceeds $5 billion annually, and continues to increase at a rapid pace,” said Doug Hardman, North American Marketing Director for Seoul Semiconductor. “Acriche products have widespread appeal, especially as eco-friendly practices dominate customer thinking. We’re excited to share news about our products with visitors to Lightfair.”

Lightfair International, one of the world’s largest annual architectural and commercial lighting trade show, alternates each year between New York and Las Vegas. This year’s event, featuring more than 475 exhibitors, is expected to attract 19,000 attendees. At last year’s show in New York, Seoul Semiconductor rolled out new ultra-small LED products and received high praise.

Seoul Semiconductor has pioneered the development and manufacturing of next-generation LED light sources since 1992. Lighting products made from Acriche LEDS are more efficient than halogen lamps, incandescent light bulbs, fluorescent lamps and most DC LED products, and are the world’s first light source that can be driven by a common alternating current power source without the need of an AC-DC converter. Mass production of a 100 lm/w Acriche lamp began during the first quarter of this year.

“Lightfair is a good opportunity for Seoul Semiconductor to actively demonstrate its new technologies to the major lighting companies and the media of the world, following ‘Light + Building’ held in Frankfurt am Main in April 2010,” said S.M. Lee, Senior Vice President of Seoul Semiconductor.

Avago launches three precision isolation amplifiers for industrial motor control and renewable energy markets

SAN JOSE, USA & SINGAPORE: Avago Technologies has announced three Miniature Precision Isolation Amplifiers with increased accuracy, bandwidth and high insulation made possible by proprietary optical isolation technology.

Based on sigma-delta analog-to-digital converters and chopper stabilized amplifiers, the new isolation amplifiers feature high gain accuracy, low temperature drift, 3.3 V/5 V output supply operation and a wide -40 to +105°C operating temperature range.

These features are delivered in a stretched SO-8 package that has a footprint 30 percent smaller than the standard DIP-8 package. When mounted on a PCB, it occupies a space that is a fraction of that for a traditional Hall Effect or transformer based isolation amplifier.

The series is implemented with a fully differential circuit topology with a gain accuracy of ±0.5 percent (ACPL-C79B), ±1 percent (ACPL-C79A), and ±3 percent (ACPL-C790). Normalized gain drift is -50 ppm/°C.
