TI intros lowest power video amplifiers

DALLAS, USA: Two new video amplifiers from Texas Instruments Inc. help manufacturers meet the demand for more energy-efficient home and portable entertainment systems.

The THS7365 is the lowest power six-channel, fixed filter video amplifier supporting HDTV and SDTV. The device delivers 21 percent lower power consumption at 5 volts (V) and 50 percent lower at 3.3 V to help manufacturers achieve ENERGY STAR compliance in set-top boxes (STBs) and Blu-ray DVD players.

The THS7319 is the lowest profile, three-channel video amplifier supporting EDTV. It delivers 25 percent lower quiescent current than alternative devices to prolong battery life in portable media devices.

Key features and benefits of THS7365:
* Integrated 6th order Butterworth fixed filter for HD and SD video. Bypass mode provides up to 250 MHz bandwidth to support full HD 1080p60 or UWXGA video.
* Six-channel operation supports composite (CVBS) video, S-video and Y'P'(B)P'(R) component video simultaneously.
* Total supply current of 21.6 mA at 5 V and 20.7 mA at 3.3 V provides the low power consumption that is important for devices seeking ENERGY STAR compliance.
* Power down disable mode reduces quiescent current to 0.1uA to save power when the system is idle.
* Wide supply and low voltage operation of 2.6 V to 5.5 V from a single supply maximizes design flexibility.

Key features and benefits of THS7319:
* Integrated 3rd order Butterworth fixed filter for EDTV provides space savings
Low quiescent current of 1.1 mA/channel and 0.15 uA in power down mode extends battery life.

* 1.5 mm x 1.5 mm x 0.40 mm tiny MicrostarCSP package reduces height by more than 30 percent for a thinner profile.

* Wide supply and low voltage operation of 2.5 V to 5.5 V from a single supply maximizes design flexibility.

The THS7365 is available today in a TSSOP-20 package that is lead-free and green (RoHS-compliant) and priced at $0.70 in 1,000-unit quantities. The THS7319 is available today in a tiny MicrostarCSP package for $0.85 in 1,000-unit quantities.

TI unveils smallest 6-A, 17-V step-down DC/DC converter

DALLAS, USA: Extending its family of easy-to-use SWIFT(TM) power management ICs, Texas Instruments (TI) has introduced the industry's smallest single-chip, 6-A, 17-V step-down synchronous switcher with integrated FETs.

The high-performance TPS54620 is 60 percent smaller than today's multi-chip converters, resulting in a complete 6-A power solution less than 195 mm2 -- one-fourth the size of a postage stamp. The 1.6-MHz monolithic DC/DC converter supports input voltages from 4.5 to 17 V, allowing it to manage space-constrained 5-V and 12-V point-of-load designs, such as a wireless base station or high-density server.

"As telecom designs become more dense and complex, they need more integrated, highly efficient power management devices that support a 12-V power rail," said Steve Anderson, senior vice president of TI's Power Management business unit. "We continue to develop smaller, more robust SWIFT converters, so designers can more quickly develop differentiated products for the market."

In addition to size improvements, the TPS54620 offers a high degree of performance and reliability, such as a highly accurate voltage reference with +/- one percent accuracy over temperature. Achieving a 95-percent power conversion efficiency and a 25 percent lower Rds(on) than previous 6-A SWIFT devices, the converter easily powers deep sub-micron TI digital signal processors (DSPs) and other embedded processors, such as FPGAs and ASICs.

Features and benefits of TPS54620
* The SWIFT device supports a 6-A continuous, 8-A peak load current, and a power stage input voltage range from 1.6 V to 17 V.
* 1.6-MHz synchronous converter integrates two high-efficiency MOSFETs (26 milliOhms and 19 milliOhms) and comes in a space-saving, thermally enhanced 3.5 mm x 3.5 mm monolithic QFN package that minimizes footprint.
* Synchronized switching frequency from a master clock eliminates beat noise in sensitive data acquisition circuitry.
* Feature-rich IC includes power-good, enable and tracking pins for sequencing.
* Broadest range of monolithic and multi-chip solutions.

TI provides the broadest range of step-down converters in the industry, including its SWIFT and discrete DC/DC converters.

In addition to the TPS54620, TI recently introduced its new TPS54418 4-A switcher with integrated FETs, which supports input voltages from 2.95 V to 6 V. The device switches up to 2 MHz, can be synchronized and achieve greater than 95-percent power efficiency in a small 3x3mm QFN package.

The TPS54620 is available in volume now from TI and its authorized distributors in a 3.5x3.5mm QFN package. Suggested resale pricing is $1.95 in 1,000-unit quantities. The TPS54418 has a suggested resale price of $2.15 in 1,000-unit quantities.

MIC, TERI light rural villages and homes through high efficiency solar LED lighting systems and LED lanterns

MUMBAI, INDIA: MIC Electronics Ltd made an announcement today that the company would provide high efficiency solar LED Lighting Systems, to rural areas.

Dr. M.V. Ramana Rao, Managing Director of MIC, said: “We will supply high efficiency solar LED lighting products to light villages. Using the power of free and abundant sunlight, MIC’s solar LED lanterns are MIC’s green energy solutions that would replace the kerosene and paraffin lanterns in each household.”

Ms Akanksha Chaurey, LaBL’s Global Head and TERI’s Director for Decentralized Energy Solutions Division, unveiled MIC’s High Efficiency Solar Lighting Systems. Other than Solar LED Lighting Products developed by MIC Electronics and certified by the Ministry of New and Renewable Energy (MNRE), high light output 3W and 5W solar LED lanterns have been selected by TERI for LaBL program.

“Over 1.6 billion people in the world lack access to electricity and 25% of them live in India. For these people, life comes to a standstill after dusk. Inadequate lighting is not only an impediment to progress and development opportunities, but also has a direct impact on the health, environment, and safety of people who are forced to light their homes with kerosene lamps, dung cakes, firewood, and crop residue after sunset. LED lanterns are more efficient and long lasting than CFL Lanterns and MIC’s commitment to the cause of developing sustainable technologies for renewable energy source is laudable.” said Ms. Akanksha Chaurey.

The path breaking initiative of MIC Electronics and TERI is fully supported by NICHIA Corporation, Japan and Texas Instruments, USA.
Makoto Takenaka San of NICHIA Corp. Japan and Amit Rao of Texas Instruments, expressed happiness over MIC Electronics’ efforts to develop solar LED lighting products and joining hands with TERI to provide better illumination and smoke-free indoor environment not only in households but also in small enterprises such as shops, local bazaars, education centers and cottage industries.

The campaign "Lighting a Billion Lives’" (LaBL) targets all communities across the world that lack access to modern and clean sources of lighting. Through this campaign, local entrepreneur-driven delivery channels are created for distribution and servicing of solar lanterns to rural communities. The campaign also provides excellent opportunity for public-private-people-partnership (P4) wherein the private sector can enhance the effectiveness of development schemes of the government, particularly in health, education and livelihoods sectors, by providing lighting through LaBL.
