TPS548B22EVM-847, 25-A Single Synchronous Step-Down Converter

Overview

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

Description

The TPS548B22EVM-PWR784 evaluation module (EVM) uses the TPS548B22. The TPS548B22 is a D-CAP3™ mode, 25A synchronous Buck converter with integrated MOSFETs. It provides a fixed 1.0V output at up to 25A from a 12V input bus.

Features

  • 25A DC Steady State Output Current
  • ±0.5% 0.9VREF Tolerance Over -40 to
  • 150°C Junction Temperature
  • True Differential Remote Sense Amplifier
  • D-CAP3™ Control Loop to Support LargeBulk Cap and/or Small MLCCs Without External Compensation
  • Eco-Mode and FCCM Selectable
  • Temp Compensated and Programmable Current Limit with RTRIP and OC Clamp ±10%

Typical applications

  • Wireless and wired communication infrastructure/ Enterprise server, switches, routers
  • Industrial PCs, automation, ATE, PLC, video surveillance
  • ASIC, SoC, FPGA, DSP core and I/O rails/ Enterprise storage, SSD, NAS
