Description

PMP20468 is an isolated flyback converter utilizing the LM5022 controller for Power-over-Ethernet applications. This design has a minimum operating input voltage of 36V, a maximum input voltage of 57V, and an output of 12V @ 2A of load current. Switching frequency is set to 420kHz. A custom Wurth transformer is used in this design.

Features
  • 36V to 57V input, 12V @ 2A output
  • LM5022 controller for an isolated flyback topology to achieve over 89% efficiency over all operating conditions
  • Compact size, slim form factor, suitable for power-over-ethernet camera applications
  • Solution size:  81mm x 38mm
  • 91% peak efficiency
