Output Voltage. This pin is the output voltage terminal; connect directly to COUT.
Input Voltage. Connect to Li-Ion battery input power source and the bias supply for the gate drivers.
Switching Node. Connect to inductor.
Enable. When this pin is HIGH, the circuit is enabled.
Power Ground. This is the power return for the IC. COUT capacitor should be returned with the shortest
path possible to these pins.
Analog Ground. This is the signal ground reference for the IC. All voltage levels are measured with
respect to this pin – connect to PGND at a single point.
