Description

2 Description
The BSR054EVM is designed as a single output DC/DC converter that demonstrates the
TPS543C20AEVM-054 in a typical low-voltage application while providing a number of test points to
evaluate the performance. It uses a nominal 12-V input bus to produce a regulated 0.9-V output at up to
40-A load current.
2.1

Typical End-User Applications

• Enterprise storage, SSD, NAS
• Wireless and wired communication infrastructure
• Industrial PCs, automation, ATE, PLC, video surveillance
• Enterprise server, switches, routers
• ASIC, SoC, FPGA, DSP core and I/O rails
2.2

EVM Features

• Regulated 0.9-V output up to 40-A, steady-state output current
• Convenient test points for probing critical waveforms
