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

PMP3162

Design files

Overview

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.

Features
  • High Efficiency (95%)
  • Generates regulated 12V bus for telecom or server applications
  • Low profile, less than 0.5 inches (12.5mm) max component height
  • Self-driven synchronous rectifiers reduce drive complexity
