11.3.2 Schottky for Current Surge Protection

To prevent the possibility of large ground currents into the TPS65982 during sudden disconnects because of

inductive effects in a cable, it is recommended that a Schottky be placed from VBUS to GND as shown in

Figure 86. The NSR20F30NXT5G is recommended.
