Upper MOSFET Floating Bootstrap Supply. A capacitor connected between BST and SW pins holds
this bootstrap 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 is required with the ADP3110A.
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.
