Overview

PMP4482 is a full featured power module reference design including output UV/OV/OC and input voltage UV protection. It provides 0.7~2V output voltage with load current up to 50A by using TPS40428 and CSD95372. The built-in temperature and current sensors improve the accuracy and eliminate discrete components. It is also stackable up to another board to support load current as high as 120 A by easy connection.This solution provides the features such as prebias startup, track, current sharing and PMBus interface for flexible configuration.

Features
  • Tracking for external signal
  • Current sharing between phases and boards
  • Pre-bias startup
  • PMBus interface for configuration & Telemetry
  • Small size:  33mm(L) x 23mm(W) x 8.5mm(H)
