The TPS546C23EVM2-746 is a two-phase buck converter with two stacked TPS546C23 devices. It uses a nominal 12-V bus to produce a regulated output at up to 70 A of load current. The TPS546C23EVM2-746 is designed to demonstrate the stacking operation of the TPS546C23 in a two-phase low output voltage application while providing a number of test points to evaluate the performance of the devices. The TPS546C23EVM2-746 can be modified to two separated single phase buck converters by changing the components assembled. Refer to the data sheet for more information on single-phase configuration.
The following warnings and cautions are noted for the safety of anyone using or working close to the TPS546C23EVM2-746. Observe all safety precautions.

Caution | Do not leave the EVM powered when unattended. |
The circuit module has signal traces, components, and component leads on the bottom of the board. This can result in exposed voltages, hot surfaces, or sharp edges. Do not reach under the board during operation.
The circuit module can be damaged by over temperature. To avoid damage, monitor the temperature during evaluation and provide cooling, as needed, for the system environment.
Some power supplies can be damaged by application of external voltages. If using more than one power supply, check the equipment requirements and use blocking diodes or other isolation techniques, as needed, to prevent damage to the equipment.
The communication interface is not isolated on the EVM. Be sure no ground potential exists between the computer and the EVM. Also be aware that the computer is referenced to the battery potential of the EVM.
