This EVM was developed prior to the USB Power Delivery Specification change back in March 2016 and therefore does not have the native hardware to support the 5, 9, 15 and 20V rails. In order to follow the new source power rules please refer to TPS65982 Designs for Supporting Voltages in USB-PD 'Power Rules' or reference the TPS65981EVM.
The TPS65986EVM is a complete reference design for USB Type-C and Power Delivery applications. It allows the user to develop various power profiles and alternate modes such as DisplayPort and debug existing USB Type-C and Power Delivery systems. In addition, when used with the DP-EXPANSION-EVM the user can emulate a full-featured USB Type-C PD host or device.
