Design files

Overview

PMP20692 is an isolated flyback converter utilizing the LM5022 for industrial applications. This design accepts PoE input voltage of 54V ± 10%. The test report here is 54V in ± 10%, 12V out @ 3A of load current.  Switching frequency is set to 250kHz. A custom transformer is used in this test report for all the scope capture.

Features
  • 54Vin±10%, 12Vout @ 3A out – IC capable of 6V to 60Vin
  • 36W isolated output
  • Peak efficiency 92%
  • High power density: 110W/6 square inches
  • Secondary soft start
