Design files

Overview

This reference design uses TPS543C20 in a stacked configuration to provide 0.85V @ 40A in a compact (21mm x 35mm) form factor with low temperature rise with no airflow. Board includes on board high speed dynamic load tester, output ripple probe interface, and test point for stability analyzer, such as Venable 2130. Internal compensation allows for design desity and simplicity.

Features
  • Stackable up to 80A
  • Internally compensated
  • Compact board layout (21mm x 35mm)
  • Less than 30C rise at 40A with no air flow
  • Rich test interface including on board high speed dynamic load
  • With airflow design has been verified to operate @75A with 45C temperature rise
