NCP81161MNTBG Datasheet PDF - ON Semiconductor

The NCP81161MNTBG is a VR12.5 compatible, synchronous buck MOSFET driver in 8 pin DFN package. This 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 3nF load with a 25ns propagation delay and 20ns 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 makes the outputs are low when supply voltage is low. It is used in Vcore power systems and desktop computers.
