PMP20676

Design files

Overview

The PMP20676 reference design is an isolated flyback converter for industrial applications utilizing the LM5022 PWM controller.  It accepts an 18V to 30V input and has a 12V/4A output.  Diode rectification is used for low cost while still maintaining good efficiency.

Features
  • 18-30V industrial input range
  • Diode rectifier for low cost
  • Peak efficiency of 90%
  • 1500Vrms isolation
