Upper MOSFET Floating Bootstrap Supply. A capacitor connected between BST and SW pins holds this boot-
strap voltage for the high--side MOSFET as it is switched. The recommended capacitor value is between
100 nF and 1.0 mF. An external diode will be needed with the NCP3418A.
Logic--Level Input. This pin has primary control of the drive outputs.
Output Disable. When low, normal operation is disabled forcing DRVH and DRVL low.
Input Supply. A 1.0 mF ceramic capacitor should be connected from this pin to PGND.
Output drive for the lower MOSFET.
Power Ground. Should be closely connected to the source of the lower MOSFET.
Switch Node. Connect to the source of the upper MOSFET.
Output drive for the upper MOSFET.
