3 Powering the TPS25750EVM

The main power supply for the EVM is the barrel jack (J9), which accepts 19 V to 20 V via a barrel jack adapter. Alternatively, the EVM can also be powered with an external power supply on SYS_PWR (TP4). The input voltage can range from 12 V to 20 V. The EVM can also run in dead battery mode and be powered from the USB Type-C™ connector. Connect a USB Type-C™ source to the USB Type-C™ port. This will cause for the TPS25750 to be powered solely by VBUS from the USB Type-C™ source connected, allowing for users to test the behavior of the TPS25750 in a dead battery scenario.
