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
