PMP9446

Design files

Overview

PMP9446 is an Isolated Flyback Converter using the LM5022 controller IC. The design accepts an input voltage of 10Vin to 15Vin (12Vin Nominal) and provides an output of 54Vout capable of supplying 0.75A of continuous current to the load. The design was built on the PMP7899 PCB, which was modified to the PMP9446 design configuration and requirements.

Features

  • Isolated Input/Output for Safety
  • High Power Density: 40W/5.6 Sq. inches
  • Small Solution Size
  • High Step-Up Ratio
  • Small device package size
  • Voltage Reference Accuracy of ±1%
