2 Description

The TPS543C20EVM-869 is a two-phase, buck converter with two stacked TPS543C20 devices. It uses a nominal 12-V bus to produce a regulated 0.9-V output at up to 80-A load current (40-A per phase). The TPS543C20EVM-869 is designed to demonstrate the stacking operation of the TPS543C20 in a two-phase, low-output-voltage application while providing a number of test points to evaluate the performance of the devices. The TPS543C20EVM-869 can be modified to two separated single-phase, buck converters by changing the components assembled. Refer to the TPS543C20 4-VIN to 14-VIN, 40-A Stackable, Synchrns Step-Down SWIFT™ Converter data sheet for more information on single-phase configuration.
