Reference Design of AC/DC Converter Using FSL106HR Green-Mode Power Switch

The reference design of AC/DC Converter (Power Supply) Using FSL106HR Green-Mode Fairchild Power Switch (FPSTM) was converted into DesignSpark PCB format and you may download the project’s files and BOM list in the Download section at the bottom.

  • Total Output Power: 2.25W
  • Two DC Outputs: 5V / 0.3A 15V / 0.05A
  • AC Input Voltage: 85VRMS – 265VRMS

This document describes the proposed solution for an universal input 4W AC/DC converter (power supply) using FSL106HR Green-Mode Fairchild Power Switch (FPSTM). The input voltage range is 85VRMS – 265VRMS and there are three DC outputs with 3.3V @ 200mA, 4.14V @ 750mA and
5.0V @ 50mA.
