Design files

Overview

PMP9256 is an isolated synchronous flyback converter utilizing the LM5122 for industrial applications. The benefit of using a synchronous flyback is higher efficiency compared to a non-synchronous flyback.

Features
  • Synchronous rectifier for high efficiency
  • Isolated design to meet safety requirements
  • Excellent regulation with opto feedback
  • Wide input operating range
  • Voltage Reference Accuracy of +/-1%
  • Synchronizable to external Clock
