30W Isolated Synchronous Flyback Converter Reference Design


Design files


PMP10506 is an isolated synchronous flyback converter using the LM5122 controller IC. The design accepts an input voltage of 9Vin to 60Vin and provides an isolated output of 5Vout capable of supplying 6A of continuous current to the load.

  • Synchronous secondary-side rectification for higher efficiency
  • Low temperature rise
  • Overload protection
  • Precision secondary-side voltage regulation
  • Isolated design for safety-critical applications
