NCP4330 Description
(S) Function “HS_DRV” is the gate driver of the high−side MOSFET. “BST” is the bootstrap pin. A 0.1 mF to 1.0 mF ceramic capacitor should be connected between this pin and the node that is mon to the coil and the two MOSFET.
NCP4330 Key Features

- PWM Operation Synchronized to the Converter Frequency
- High Gate Drive Capability
- Bootstrap for N-MOSFET High-Side Drive
- Over-Lap Management for Soft Switching
- High Efficiency Post-Regulation
- Ideal for Frequencies up to 400 kHz
- This is a Pb-Free Device
