Design files

Overview

This reference design showcases a dual output primary-side regulated flyback converter, which covers an input voltage range of 8.0 V to 36 V. The output voltage of the two isolated outputs is 17.5 V each with a maximum load current of 100 mA.

Features
  • Power stage withstands surge voltages up to 36 V
  • Input filter decreases the reflected ripple
  • Two separately isolated outputs increases the range of applications
  • Primary-side regulation and integrated FET reduces the bill of materials
