Using the TPS53647: PWR710-EVM, 4-Phase, D-CAP+
Step-Down, DC-DC Analog with PMBus Interface
The PWR710-EVM evaluation module (EVM) uses the TPS53647 controller. The controller is 4-phase, D-
CAP+™ synchronous buck driverless controller with PMBus™ interface. The device operates using a
voltage supply between 4.5 V and 17 V. The controller allows programming and monitoring via the PMBus
interface. This PWR710-EVM uses the CSD95372B, Synchronous Buck NexFET™ Smart Power Stage
(SLPS499) device as the power stage.

The PWR710-EVM operates as a single output converter. The nominal 12-V bus produced a regulated,
1.0-V output at up to 120 A of load current. The PWR710-EVM demonstrates the controller in a typical
low-voltage high-current application while providing a number of test points to evaluate the performance of
the controller. Refer to TPS53647 (SLUSC39) datasheet for more information on multi-phase
configuration.
