LOW-NOISE DC/DC CONVERTER WITH CONTROLLED DIODE CONDUCTION

摘要

The synchronous rectifier MOSFET in a Buck or boost DC/DC converter is operated as a current source rather than being turned off, thereby reducing undesirable losses in efficiency, the generation of unwanted electrical and radiated noise, and numerous other potential problems, particularly when the converter is operating in a light-load condition. ® KIPO & WIPO 2009
