Description

This reference design generates a 28V/5A output from a 36V to 75V telecom input. The UCC2897A controls an active clamp forward converter power stage. The output is adjustable within a 22V to 32V range.  The UCC27511 is used to drive synchronous rectifiers, and provides for a highly efficient design. This design is laid out on a circuit board with pin placement that is compatible with a 1/4 brick footprint and achieves efficiencies over to 94%.  It uses only surface mount components, including ceramic output capacitors.
