200-V to 480-V DC input, 22-W flyback isolated power supply reference design

PMP41012

Design files

Overview

This reference design provides an isolated 15-V and 22-W outputs with flyback topology with LM51561-Q1 controller. The power supply can be powered from the 200-V to 480-V DC input. This primary-side regulation design does not contain an optocoupler and uses a dual random spread spectrum which reduces EMI.

Features
  • Wide input range: 200-V to 480-V DC
  • Primary-side regulation without optocoupler
  • Compact form factor with isolated flyback
  • Dual random spread spectrum to reduce EMI
