Description

PMP7991 is a quasi-resonant isolated flyback using the LM5023 controller IC. The design accepts an input voltage of 85VAC to 265VAC and provides a selectable output of 12Vout or 5Vout capable of supplying 2A of current to the load. The quasi-resonant switching scheme helps to reduce EMI.

Features
  • Isolated flyback converter
  • Wide input range suitable for worldwide AC input condition
  • Output is switch selectable for 5V or 12V at 2A
  • Quasi-resonant switching for low EMI
