Article: Simple circuit replaces and improves on power modules at less than half the price--Design Note 347.(design notes)(Advertisement)

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 LT[R]1952 changes that. It simplifies the design of a high performance synchronous single switch forward converter enough to make it a feasible and straightforward cost-cutting alternative to a power module.

A synchronous forward converter is a good choice for output voltages in the 1.2V to 26V range. In ...
