pictures, and block diagrams are provided as necessary. 5.1 Switch, Push Button, Connector, and Test Point Descriptions Components described in this section are listed with respect to the EVM from left to right and top to bottom. Related components ...

Out of the box, the TPS65988EVM has jumper configuration for a TPS65988 device. With this configuration, the two internal power paths are configured as Source paths for their respective Type-C ports. The two external power paths are configured as Sink paths for their respective Type-C ports. When using the TPS65988EVM, u ...

To use the TPS65988EVM to perform as a TPS65987D, the jumpers on J11 and J12 needs to be adjusted. Place a jumper on J12 to short the two VBUS nodes together. In this use case, one of the internal power paths is used as a source path and the other internal power path is used as a sink path. The TPS65987D supports one Ty ...

To emulate a TPS65987S with the TPS65988EVM, the jumpers on J11 need to be adjusted. The TPS65987S supports one Type-C port and contains one internal power path. When using the TPS65988EVM to emulate a TPS65987S, the internal power path (PPHV1) is used as the Source Path and one of the external power paths is used as th ...

5.1.2 DP Source Receptacle The DP source receptacle routes DP lanes for port A/B, AUX for port A/B, HPD for port A/B, as well as DP port A/B select. The HD3SS3412 is used to MUX the DP source from the full-size DP receptacle to the USB Type-C alternate mode MUX (TUSB546) for port A/B. Only one of the ports ...
