VBUS (pins 26 and 27)

Place the VBUS decoupling capacitor (C37) as close as possible to the VBUS pin of the excernal NMOS transistor (Q8), the capacitor does not need to be on the same layer as the device. The VBUS power plane need to be sized to support up to 3A o fcurrent if the 5V power path is utalized. If this 5V power path is not utilized, then the power path can be sized to support 100mA of current. When connecting the VBUS pins (pins 26 and 27) plane to a different layer, use a minimum of 3 vias per layer change.

At the Type-C port/connector, it is recommended to use minimum of 6 vias from the connector VBUS pins for layer changes. Place the 10nF caps (C2, C3, C4, and C5) as close as possible to the connector VBUS pins as shown in figure 10-22.

When implemented with the TPD4S480, the TPS26750 does not require an external TVS protection device, but the power switch used in the system may require the addition of a TVS protection diode. Please refer to the datasheet of the switch selected to ensure that any protection requirements are met.

The VBUS line of the type C connector needs to be routed to the external power path in a manner that supports it's current and voltage needs. Please refer to the datasheet of the switch selected to ensure that any routing and current requirements are met.
