Layout constraints
As the VBUS path can carry up to 3 A, power track between DC-DC, Power MOS and Type-C connector is large
enough.
Special care must be taken for DC-DC layout and thermal dissipation.
The STUSB4710A monitors VBUS and discharges the path. The monitoring signal should be separated from the
power signal and QFN exposed pad must be connected to global GND plane through vias to allow thermal
conduction.
