The TPS546B24AEVM-2PH is a two-phase buck design stacking two TPS546B24A devices. It designed for a nominal 12-V bus and to produce a regulated 0.8-V output at up to 40 A of load current. The TPS546B24AEVM-2PH is designed to demonstrate stacking operation of the TPS546B24A in a two-phase, low-output voltage application while providing a number of test points to evaluate the performance of the devices. The TPS546B24AEVM-2PH can be modified to single-phase buck converters by changing the components assembled. See Section 4.3 for more information on single-phase configuration.
