NCP81161
VR12.5 Compatible
Synchronous Buck MOSFET
Drivers
The NCP81161 is a high performance dual MOSFET gate driver
optimized to drive the gates of both highâside and lowâside 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 antiâcrossâconduction and power saving operation
circuit can provide a low switching loss and high efficiency solution
for notebook and desktop systems. Bidirectional EN pin can provide
a fault signal to controller when the gate driver fault detect under
OVP, UVLO occur. Also, an underâvoltage lockout function
guarantees the outputs are low when supply voltage is low.
