AN881
Application note
Low cost active clamp for high frequency
applications

Introduction
Purpose of this application is to describe a singleswitch forward converter with two outputs,
5V- 20A and 12V-4A, with an active clamp system.
This is an application close to personal computer and logic cards power supplies. For the
approached output power level, 150W, the single transistor forward converter represents, in
addition to the high frequency operation, the best soluti
