Product Summary

This document gives guidance for the design of a singleended forward converter with DPA-Switch in applications
that require a single output voltage. It is intended for systems
engineers and circuit designers who wish to become familiar
with the capabilities and requirements of DPA-Switch in
DC-DC applications. This application note provides background
material that will assist users of the DPA-Switch DC-DC forward
converter design utility that is included in the software design
tool, PI Expert. Subsequent application notes will provide
comprehensive procedures for designs of greater complexity.
Designers are advised to check Power Integrations? website at
www.powerint.com for the latest application information and
design tools

Features

? Low component count
? High ef?ciency (typically >91% with synchronous
recti?cation)
? Built in soft-start to minimize stress and overshoot
? Built in accurate line under-voltage detection
? Built-in accurate line overvoltage shutdown protection
? Built in adjustable current limit
? Built-in overload and open loop fault protection
? Built-in thermal shutdown
? Programmable duty cycle reduction to limit duty cycle
excursion at high line and transient load conditions
? Very good light-load ef?ciency
