Secondary control ICs increase computer power supply efficiency.(POWER ELECTRONICS CONFERENCE HEATS UP DALLAS)
Design News, May, 2006
Philips Electronics GreenChip SR products, the TEA1761 and TEA1762, are secondary control ICs that integrate both synchronous rectification (SR) and primary feedback/control in a single unit. Designed for Philips' silicon on insulator (SOI) process, which accommodates a wide voltage range, the TEA1762 includes additional protection circuitry that requires an SO14 package and the lower cost TEA1761 comes in a SO8 package. When used as the secondary control IC for notebook adapters, the GreenChip SR improves the efficiency of laptop computer adapters by three to five percent.
