NCP81146 Datasheet | onsemi

VR12.5 patible Synchronous Buck MOSFET Drivers The NCP81146 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 n F 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 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 under- voltage lockout function guarantees the outputs are low when supply voltage is low.
