NCP3418A, NCP3418, Dual Bootstrapped 12V MOSFET Driver

Pin Symbol 1 BST 2 IN 3 OD 4 VCC 5 DRVL 6 PGND 7 SW 8 DRVH 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 mF.

NCP3418, NCP3418A Dual Bootstrapped 12 V MOSFET Driver with Output Disable The NCP3418 and NCP3418A are dual MOSFET gate drivers optimized to drive the gates of both high side and low side power MOSFETs in a synchronous buck converter.

Each of the drivers is capable of driving a 3000 pF load with a 25 ns propagation delay and a 20 ns transition time.

With a wide operating voltage range, high or low side MOSFET gate drive voltage can be optimized for the best efficiency.
