6 Using the TPS65994EVM
This section discusses the pre-loaded or recovery firmware, getting started, and debugging the EVM.
6.1 Powering the TPS65994EVM
The main power supply for the EVM is the barrel jack (J2), which accepts 19 V to 20 V via a barrel jack adapter.
The EVM can also be powered with an external power supply on SYS_PWR (TP7). The input voltage can range
from 5 V to 20 V, but the appropriate power profile for PP_EXT should be configured in the firmware using the
configuration tool. The EVM can also be bus-powered from the USB Type-C connector and accepts 5 V to 20 V
on VBUS, depending on the sink configuration.
6.2 Firmware Configurations
Out of the box, the TPS65994EVM is configured to emulate a dual-port laptop computer. For each port, the
internal power switch is configured for sourcing, and the external high current power switch is configured for
sinking. Both ports are configured for data DFP.
