6W 48V-72Vin Fly-Buck with Primary and Isolated Secondary Load Reference Design

PMP30082

Design files

Overview

The PMP30082 reference design shows two stage power supply. The first stage is a fly-buck topology that converts an input of 48V-72V to a primary output voltage of 12V with a maximum load current of 250mA and to an isolated secondary output voltage of 24V with a load current of 160mA. Two Buck converters are connected to the primary 12V rail. One generates 5V with 400mA load current, the other one generates 3.3V with 100mA load current.

Features
  • Built and tested
  • Non-isolated and isolated rails with one primary stage
  • Primary side regulated isolated output
  • Wide input voltage range
  • Small form factor
