Synchronous rectifiers versus Schottky diodes: a comparison of the losses of a synchronous rectifier versus the losses of a Schottky diode rectifier

Abstract

A brief description of the differences in current flow through a MOSFET and a Schottky diode establishes the basis for a prediction of future device performance. Two different forward converter designs are used to illustrate the expected performance differences between the synchronous rectifier and Schottky diode designs. The current levels were selected to provide the designer with a more intuitive understanding of which applications benefit most from each type of design.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
