PMP20129

Design files

Overview

PMP20129 is an isolated synchronous flyback converter with a 3.3V/5A output.  The 36-60V input range is suitable for most telecom and Power over Ethernet (PoE) applications that require high efficiency.

Features
  • 88% efficiency with 48V input and 5A load
  • 1500VRMS isolation for telecom or PoE
  • Optocoupler feedback for excellent line/load regulation
