10-VDC to 30-VDC input PSR flyback converter with dual-output reference design

Design files

Overview

This reference design provides two isolated voltages (6 V at 200 mA, 12 V at 200 mA) from a DC-input supply (10 V - 30 V). By means of zero ohm resistors, a flexible transformer can be configured to change the turns ratio and output voltages without any layout change. The converter enables an isolated DC/DC solution with high density and low component count. No auxiliary transformer winding is required and a 100-V rated primary-side switch is integrated.

Features
  • Provides compact solution due to elimination of optocoupler and transformer auxiliary winding
  • Programmable soft start limits the inrush current drawn by the power supply
  • Rated for up to 200 mA of load current
  • Resistor divider to EN/UVLO to faciltate programmable input voltage UVLO
  • Tested design with available design files and test report
  • Flexible transformer used for easy output voltage change
