NCP5911 Datasheet, PDF (1/9 Pages) ON Semiconductor – IMVP7.0 Compatible Synchronous Buck MOSFET Driver

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.
Features
• Faster Rise and Fall Times
• Adaptive Anti−Cross−Conduction Circuit
