Overview

PMP20497 is an isolated flyback converter utilizing the LM5022 for industrial applications. This design accepts input voltage of 12V. The test report here is 12Vin/~54V out @ 2A of load current.  Switching frequency is set to 100kHz. A custom Pulse transformer is used in this test report for all the scope capture.

Features
  • 12Vin, 54Vout @ 2A out – IC capable of 6V to 60Vin
  • 110W isolated output
  • Peak efficiency 92%
  • High power density: 110W/6 square inches
  • Cycle-by-cycle current limit
