TPS546C25EVM-1PH 4V to 18V, 35A, Buck Converter with
PMBus and Telemetry Evaluation Module
Description
The TPS546C25EVM-1PH is a single-phase
buck design using the TPS546C25 device. The
TPS546C25EVM-1PH is designed for a nominal 12V
bus and produces a regulated 1.2V output at up to
35A of load current. The TPS546C25EVM-1PH is
designed to demonstrate operation of the TPS546C25
in a single-phase, low-output voltage application,
while providing a number of test points to evaluate
the performance of the devices. See
Measurement for more information on single-phase
configuration.
