Synchronous forward converter

Introduction

Prefabricated power modules offer a simple but expensive solution to the complicated problem of efficiently converting high distribution voltages to the isolated low voltages required by digital ICs. Build-your-own solutions are much cheaper, but time constraints may drive even seasoned power supply designers to the power module shelf. The LT1952 changes that. It simplifies the design of a high performance synchronous ...
