Design files

Overview

PMP20551 is an isolated flyback converter utilizing the LM5022 for industrial applications. This design accepts PoE input voltage of 12V to 60V The test report here is tested at 12V out @ 3A of load current.  Switching frequency is set to 100kHz. A custom transformer is used in this test report for all the scope capture.
