36Vdc-75Vdc Input, 6V @ 20A Output, Active Clamp Forward PMP4123 (ACTIVE)
See the Important Notice and Disclaimer covering reference designs and other TI resources.
The PMP4123 reference design provides 6V at 120W from a standard 48V telecom input with greater than 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 quarter-brick footprint.
