PMP20541

Design files

Overview

The PMP20541 reference design is an isolated synchronous flyback converter with a 12V/4A output.  The 36-60V input is suitable for most telecom and PoE applications.  The UCC2897A PWM controller has dual drivers for precise control of the primary FET and synchronous FET.

Features
