NCP3488, MOSFET Driver

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 mF.

An external diode is required with the

www.DataSheet4U.com NCP3488 MOSFET Driver with Dual Outputs for Synchronous Buck Converters The NCP3488 is a single Phase 12 V MOSFET gate driver optimized to drive the gates of both high side and low side power MOSFETs in a synchronous buck converter.

The high side and low side driver 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
