Reference Design of Non-Isolated AC/DC Converter Using FSL136HR Power Switch

The reference design of non-isolated AC/DC converter using FSL136HR power switch was converted into DesignSpark PCB format and you may download the project’s files and BOM list in the Download section at the bottom.

  • AC Input Voltage: 85VRMS – 270VRMS
  • Total Output Power: 2.25W
  • Two DC Outputs: 5V / 0.3A 15V / 0.05A

This document describes the proposed solution for a PSU using FSL136HR Fairchild Power Switch (FPSTM). The input voltage range is 85VRMS – 270VRMS and there are two DC outputs with 5V / 0.3A and 15V / 0.05A.
