Description

The PMP5753 reference design provides 5V at 125W from a standard 48V telecom input with greater than 94% efficiency. This design uses the UCC2897A active clamp controller along with self-driven synchronous rectifiers. Texas Instruments NexFET technology is used for the synchronous rectifiers, improving the efficiency by nearly 2% over conventional MOSFETs. The output voltage can be adjusted up to 7V.
