This application note describes how to use Schottky diodes in the avalanche region to improve the performance of the converter.
This document explains how to determine if a Schottky diode can work in the avalanche area within a Switch Mode Power Supply (SMPS). It provides a simple method to estimate the maximum avalanche peak power and an accurate method using Pspice simulation to estimate maximum average avalanche power losses. These methods help designers optimize the choice of Schottky diodes to improve converter efficiency.
