TPS549B22EVM-847, 25-A Single Synchronous Step-Down Converter With Full Differential Sense and PMBus

Overview

TopologyBuck Converter
Input voltage5-14 V
Output 11 V / 25 A

Description

The TPS549B22EVM-847 evaluation module (EVM) uses the TPS549B22. The TPS549B22 is a D-CAP3™ mode, 25A synchronous buck converter with Full Differential Sense and PMBus™. The converter provides a fixed 1.0V output at up to 25A from a 12V input bus.

Features

  • D-CAP3™ control mode for fast transient response and low external component count
  • 0.5%, 900-mV reference voltage and differential remote sense enable tight output voltage regulation accuracy
  • Output voltage margining and fault reporting via PMBus
