High-Efficiency Adjustable Output Synchronous Boost Converter Reference Design

PMP10538

Design files

Overview

PMP10538 is a Single-Phase Synchronous Boost Converter using the LM5122 controller IC. The design accepts an input voltage of 18Vin to 20Vin and provides an output of 30Vout to 54Vout, capable of supplying 1.7A of continuous current to the load or 0A to 3.4A Max. The output voltage can be adjusted between 30Vout and 54Vout by driving the Vadj. input of the Op-Amp circuit between 0V and 3V.

Features

  • High efficiency design
  • Adjustable output voltage
  • Cycle-by-Cycle Current limit with programmable hiccup mode overload protection
  • Precision voltage reference accuracy of ±1%
  • Synchronizable to external clock
