Surge Protection
Output (PPHV) Protection
...
Seeing as this board is primarily intended for debugging RPi Interface Rev C, which includes a buck converter with large bulk capacitance, we will need to implement surge protection as recommended by TI.
Input (VBUS_IN) Protection
While the source device should do most of the regulation, TI recommends a (Schottky) diode be placed from VBUS to ground. This is due to the possibility of large ground currents during sudden disconnects due to inductive effects in a cable. They recommend their TVS2200 product.
