INFORMATION
Theory of Operation High−Side Driver
The NCP3488 is a single phase MOSFET driver designed for driving two N.
Pin No. 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 1.0 .
