Description

PMP10516 is an Isolated Flybuck Converter using the LM25017 regulator IC. The design accepts an input voltage of 20.4Vin to 28.8Vin (40Vin Max. Peak) and provides three isolated outputs. The +5Vout rail is regulated for precision using the LP2951 linear regulator.

Features
  • Multiple isolated outputs
  • Primary side regulation without opto, good cross regulation, within +/-5%
  • Low BOM count & cost, compact solution size
  • Constant On Time control, no loop compensation required, and fast transient response
  • LM25017 wide vin range
