NCP5901DR2G

The NCP5901DR2G is a dual high performance 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 guarantees the outputs are low when supply voltage is low.

• Faster rise and fall times
