Evaluation Module
Description
The TPS546E25EVM-1PH is a single-phase
buck design using the TPS546E25 device. The
TPS546E25EVM-1PH is designed for a nominal 12V
bus and to produce a regulated 1.2V output at up
to 50A of load current. The TPS546E25EVM-1PH is
designed to demonstrate stacking operation of the
TPS546E25 in a single-phase, low-output voltage
application while providing a number of test points
to evaluate the performance of the devices. The
TPS546E25EVM-1PH can be modified to single-
phase buck converters by changing the components
assembled. See Tip and Barrel Measurement
more information on single-phase configuration.
