NCP81161: MOSFET Driver, VR12.5 Compatible, Synchronous Buck

Description: The NCP81161 is a high performance dual MOSFET gat...
  • 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.
