Schottky Diode Selection in Asynchronous Boost Converters

Texas Instruments

Published Date: 09/06/2016

Description

Asynchronous boost converters require a Schottky diode as the rectifying element due to the diode's low forward voltage and fast turn-on time. Because of these characteristics asynchronous boost converters can have as good as, or better efficiency, than synchronous boost converters. This is especially true when the boost conversion ratios (VOUT/VIN) are high, and the Schottky diode conduction time is low.
