High-Power (250-W)Boost DC/DC Reference Design for 48-V Output Industrial and Telecom Applications

PMP7118

Design files

Overview

This high power step-up DC-DC employs a controller with a  low gate charge external MOSFET to supply 48V output  for  loads up to 250 W from a 24-V source.

Features
  • TPS40210 control IC with integrated low-side gate driver
  • Low gate charge (Qg) NexFETs minimize power losses
  • Fixed frequency current-mode control with internal slope compensation
  • Hiccup over-current protection
  • Built and tested circuit design
