Description

The PMP4844 reference design provides an isolated 24V output at 120W from an 18V to 54V telecom input with up to 94% efficiency. This design uses the UCC2897A active clamp controller along with an ISO721 digital isolator and TPS28225 to drive synchronous rectifiers. The circuit is built in an industry standard Half-Brick footprint.
