Function
Output drive for upper MOSFET.
Ground supply
CMOS level input signal. Controls both output drives.
Synchronous enable. When logic is high, the low-side driver is enabled.
Output drive for lower MOSFET.
Input power supply
Floating bootstrap supply for the upper MOSFET
Floating GND for the upper MOSFET. V_S is connected to the buck switching node and the source side of the upper MOSFET.
