Reference Design of AC/DC Converter Using FSGM300N Green-Mode Power Switch

The reference design of AC/DC Converter (Power Supply) Using FSGM300N Green-Mode Fairchild Power Switch (FPS) 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 – 265VRMS
• One DC Output: 13.7V @ 1.5A (switchable to 10.7V)

• AC Input Voltage: 85VRMS – 265VRMS

This project describes the proposed solution for an universal input 20W AC/DC converter (power supply) using FSGM300N Green-Mode Fairchild Power Switch (FPSTM). The input voltage range is 85VRMS – 265VRMS and there is one DC output with 13.7V @ 1.5A (switchable to 10.7V).
