PMP22170 Reference Design

Texas Instruments

Two output flyback power supply reference design for EV motor/generator inverter applications


This flyback converter reference design supplies a non-isolated 5-V/0.25-A regulated output and an isolated 10-V/1.5-A unregulated output voltage. It uses primary-side regulation to reduce component count and operates over a wide automotive input voltage range of 5 V to 40 V. 

  • Primary-side regulation reduces component count and eliminates need for an opto-couplerExcellent 10-V output voltage regulation over full input range with typical loadsEfficiency greater than 81% from 12-V input with typical loadsCompact size (78 mm x 48 mm) minimizes required PCB area
  • Inverter & motor control
