Description

PMP20058 is an isolated flyback converter utilizing the LM5022 for industrial applications. This design has a minimum operating input voltage of 8V and a maximum input voltage of 18V. The test report here is for 8V, 12V and 18Vin/~54V out @ 1.5A of load current.  Switching frequency is set to 100kHz. A custom Coilcraft transformer is used in this test report for all the scope capture.

Features
  • 8V to 18Vin, 54Vout @ 1.5A out – IC capable of 6V to 60Vin
  • 81W isolated output
  • Peak eficiency 93%
  • High power density: 81W/5.6 square inches
  • Cycle-by-cycle current limit
