Universal Input to 12V@670mA & -10V@50mA Isolated Flyback with Integrated Switch Reference Design

Description

A quasi-resonant primary-side regulated Flyback supplies an isolated output 12V @ 670mA and non-isolated output -10V @ 50mA from universal input voltage (90Vac to 270Vac). The controller integrates 700V FET and the board is able to withstand up to 350VAC without damage and switches OFF for Vin > 285VAC.

Features
  • Simple isolated PSR flyback converter with integrated 700V FETCompact solution supplies 8.5W with almost flat efficiency (70%...81%) from 5% to 100% loadOpto-less topology increases the reliability of the power supplyGood cross-regulation performance between outputs (+/-5% on main output)
Applications
  • Wired control
