For getting that Energy Star rating, the ZXGD3104N8 25V synchronous MOSFET controller for power supply designs of 90W and above enables the replacement of inefficient Schottky diodes in flyback converters. This increases power supply efficiency by as much as 3.5% through a reduction in rectifier losses to 70%. As a result, the device helps power supplies attain the 87% Energy Star V2.0 rating. Price for the ZXGD3104N8 is $0.50 each/10,000. For further details, contact Glen Wynn at DIODES INC., Dallas, TX. (972) 385-6292.
