Overview

The TPS544B20EVM-634 is designed to help the user easily evaluate and test the operation and functionality of the TPS544B20 buck converter. The EVM converts a 4.5-V to 18-V input voltage to a regulated 1.0-V output voltage that delivers up to 20 A in a 5-mm x7-mm QFN package. The output voltage on this board is marginable and trimmable via PMBus using the Fusion Digital Power™ Designer.

Features
  • D-CAP™ control mode for fast transient response and low external component count
  • 0.5%, 600-mV reference voltage enables tight output voltage regulation accuracy
  • Output voltage margining and fault reporting via PMBus
