SemiApps Readers Select Best Chip Solutions for Energy Conservation

UNIONDALE, NY--(Marketwire - May 7, 2008) - Hearst Electronics Group announced today the results of the first Green Apps contest conducted by, the premier solutions resource for engineers building next-generation electronics systems.

The Green Apps contest, judged by engineering users of, is designed to showcase the unique and powerful contributions of semiconductor solutions to energy conservation and hazardous-waste reduction in a variety of applications. Nearly 600 electronics engineers weighed in with their opinions on the potential "green impact" of various solutions entered in the contest by semiconductor manufacturers.

Gold Medal: Texas Instruments

Solution: Single-Chip Interleaved PFC Controllers (UCC28070/ UCC28060), the first single-chip, interleaved power factor correction (PFC) control circuits for multi-kilowatt communications, server and industrial systems. The new UCC28070 two-phase, average current-mode controller allows designers to simplify power design, reduce total harmonic distortion, increase system reliability and achieve a greater than 0.95 power factor rating, which improves energy efficiency.

    be used widely" … "A low-cost, high-reliability IPFC such as this one can
    have a huge impact" … "Vibrant green awareness, great effort" … "Can save
    substantial amounts of energy since it improves efficiency of big systems"
    … "Potential to offer greatest overall power savings worldwide" … "Killer
    app, we're talking megawatts here" … "This chip will be of great importance
    in the future" … "Smart management of high power = high power savings" …
    "TI continues to make great progress in the race for green applications"

Silver Medal (Tie): Freescale

Solution: Li-Ion battery charger ICs (MPC3467x family) which offer exceptionally high accuracy for output voltage and charging current over temperature to optimize the life of Li-Ion batteries, which, in turn means that fewer batteries end up in landfills.

Silver Medal (Tie): Fairchild Semiconductor

Solution: Green FPS Power Switch (FSFR2100), designed to increase power efficiency and system reliability in resonant converter designs. Offers a system-in-a-package approach that integrates everything necessary to build reliable and efficient resonant converters.

Bronze Medal: Marvell

Solution: Digital PFC Controllers for AC-DC Power Supplies (88EM8041/ 88EM8011). These DSP-based solutions are designed to cut energy usage by up to 50 percent. Notebook adapters using the Marvell 88EM8041 can be approximately one-third smaller and lighter than current notebook adapters.

Said Bill Barron, Vice President and Publishing Director of Hearst Electronics Group: "We believe that the semiconductor industry can have the greatest potential impact on the environmental crisis facing the world by providing ingenious solutions both to energy conservation and hazardous-waste reduction. The Green Apps contest will heighten the profile of the semiconductor industry's role and will help systems designers choose the right solutions based on the opinion of their peers.

"In addition to the four vendors acknowledged above, we'd like to also thank Analog Devices, Altera, International Rectifier, Intersil, Linear Technology, Maxim Integrated Products, National Semiconductor, Power Integrations and Silicon Laboratories for their entries in the contest."
