PMP41009

350-V to 1000-V DC input, 56-W flyback isolated power supply reference design

PMP41009

Design files

Overview

This reference design provides isolated 14-V and 56-W outputs with a quasi-resonant flyback topology. The power supply can be powered from the 350-V to 1000-V DC input. This design uses cascode MOSFETs and flyback controller UCC28740-Q1. The line and load regulation are regulated to within ±1% precision. The peak efficiency is 84.6% at 1000-V input and 56-W output.

Features
  • Wide input range: 350-V to 1000-V DC
  • High-precision output voltage
  • Peak efficiency 84.6% at 1000-V input and 56-W output
  • Quasi-resonant mode controller improves EMI performance
