Description

This reference design generates an isolated 3.3V/10A output from a standard 48V telecom bus input. The UCC2897A is used to control an active clamp forward topology with self-driven synchronous rectifiers. The electrical components fit into the area of a standard 1/8th brick footprint. Peak efficiency is over 92%.
