NCP5911

IMVP7.0 Compatible

Synchronous Buck MOSFET

Driver

The NCP5911 is a high performance dual MOSFET gate driver

optimized to drive the gates of both high−side and low−side power

MOSFETs in a synchronous buck converter. It can drive up to 3 nF

load with a 25 ns propagation delay and 20 ns transition time.

Adaptive anti−cross−conduction and power saving operation circuit

can provide a low switching loss and high efficiency solution for

notebook systems.

A bidirectional Enable pin can provide a fault signal to the

controller when the gate driver detects an undervoltage lockout. The

UVLO function guarantees the outputs are low when the supply

voltage is low.
