Texas Instruments TPS543B20EVM-054

25-A Fixed Frequency Non-Compensation Stackable Syncronous Buck Converter Evaluation Module

Overview

TopologyBuck Converter
Input voltage5-15 V
Output 10.9 V / 25 A
IC revisionB

Description

The BSR054EVM is designed as a single output DC-DC converter that demonstrates theTPS543B20EVM-054 in a typical low-voltage application while providing a number of test points toevaluate the performance. It uses a nominal 12-V input bus to produce a regulated 0.9-V output at up to25-A load current.

Features

  • Internally compensated advanced current mode control minimizes external component count while maintaining true fixed frequency operation
  • Pin-strap selectable switching frequency with optional frequency synchronization
  • 4.1-mΩ / 1.9-mΩ integrated MOSFETs for high efficiency up to 25 A

Typical applications

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