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 SemiApps.com, the premier solutions resource for engineers building next-generation electronics systems.

The Green Apps contest, judged by engineering users of SemiApps.com, 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.
