The TPS546D24SEVM-2PH evaluation module (EVM) is a two-phase buck converter with two TPS546D24S devices. The TPS546D24S device is a stackable synchronous buck with PMBus® interface that can operate from a nominal 2.95-V to 16-V supply. The device allows programming and monitoring through the PMBus interface.
Two TPS546D24S devices are configured as a two-phase buck converter in factory default. Output current is evenly distributed in the two devices; both the negative and positive output terminals are connected together.

The TPS546D24SEVM-2PH is a two-phase buck design using two stacked TPS546D24S devices. The TPS546D24SEVM-2PH is designed for a nominal 12-V bus and to produce a regulated 0.8-V output at up to 80 A of load current. The TPS546D24SEVM-2PH is designed to demonstrate stacking operation of the TPS546D24S in a two-phase, low-output voltage application while providing a number of test points to evaluate the performance of the devices. The TPS546D24SEVM-2PH can be modified to single-phase buck converters by changing the components assembled. See Tip and Barrel Measurement for more information on single-phase configuration.
