APPLICATION NOTE 652
Synchronous Rectification Aids Low-Voltage Power Supplies
Synchronous rectifiers can improve switching-power-supply efficiency, particularly in low-voltage low-power
applications. This article compares synchronous rectifiers to Schottky-diode types and illustrates some circuit
tricks useful in their application.

To be successful, the next generation of portable products, such as personal communicators and digital
assistants, will have to provide at least 12 hours of operation between battery charges. Most of the progress
toward this 12-hour goal must come from RF, computer, and battery
