NCP81161 Datasheet VR12.5 Compatible Synchronous Buck MOSFET Drivers

Manufacturer: onsemi

Overview: 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 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 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.
