INFORMATION
Theory of Operation
The NCP3420 are single phase MOSFET drivers designed for driving two N−channel MOSFETs .
SO−8 1 DFN8 1 Symbol BST Description 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 .
