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 Tip and Barrel Measurement for more information on single-phase configuration.
