NCP81145 Datasheet Text
VR12.5 patible Synchronous Buck MOSFET Driver
The NCP81145 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.
The UVLO function guarantees the outputs are low when the supply voltage is low.
