Design files

Overview

The PMP5454 reference design provides 3.3V at 50W (15A) from a standard 48V telecom input with greater than 92% efficiency. This design uses the UCC2897A active clamp controller along with TI CSD16414Q5 NexFET synchronous rectifiers. All components of this design fit within a 2.3" by 0.9" (1/8 brick) area of the circuit board.
