Multiport Isolated Output Flyback Solution Reference Design Featuring the LM3481

PMP10725

Design files

Overview

PMP10725 is an isolated flyback solution which accepts an input voltage of 15 to 36VIN and provides multiport output to the load. This reference design compares primary and secondary control solutions. With primary control, it can achieve higher efficiency with lower BOM cost, but the regulation performance is not so good. With secondary control, it can achieve great load regulation performance by controlling the 24V-rail voltage. This LM3481 flyback reference design can be used for supplying the digital output module in industrial PLC application.

Features
  • Multiport isolated output
  • Primary control with low BOM cost
  • Secondary control with great regulation performance
  • Peak current mode control
  • Flexible for other isolate application
