36V-72Vdc Input: 12V/200W Active Clamp Forward - Reference Design

Texas Instruments

Description

This reference design generates a 12V/16A output from a standard 48V DC telecom input. The UCC2897A controls an active clamp forward converter power stage. The low gate charge and low RDSon of the CSD19533Q51: implemented as self-driven synchronous rectifiers: allow this design to achieve a peak efficiency of 95%. The compact UCC27511 drivers simplify the gate drive circuitry for the synchronous rectifiers.
