Design files

Overview

The PMP9431 reference design is a high-efficiency single-phase synchronous boost converter using the LM5122 controller IC. The design accepts an input voltage of 12Vin to 50Vin and provides an output of 54Vout capable of supplying 2.5A of current to the load.

Features
  • High efficiency design
  • High power density
  • Synchronizable to external clock
  • Hiccup-mode overload protection
  • Precision voltage reference accuracy of +/-1%
