Description

This reference design generates a 6V/31A output from a wide range 18V to 60V DC telecom input.  The UCC2897A controls an active clamp forward converter power stage.  The low gate charge and low RDSon of the CSD18540Q5B, implemented as self-driven synchronous rectifiers, allow this design to achieve a max load efficiency over 94%.  The compact UCC27511 drivers simplify the gate drive circuitry for the synchronous rectifiers.

Features
  • High Efficiency (over 95%)
  • Low profile, less than 0.5 inches (12.5mm) max component height
  • Self-driven synchronous rectifiers reduce drive complexity
