NCP5901 VR12 Compatible Synchronous Buck MOSFET Drivers

Pin No. 1 2 3 4 5 6 7 8 9 Symbol BST PWM EN VCC DRVL GND SW DRVH FLAG Description Floating bootstrap supply pin for high side gate driver. Connect the bootstrap capacitor between this pin and the SW pin. Control input. The PWM signal has three distinctive states: Low = Low Side FET Enabled, Mid = D.

NCP5901 VR12 Compatible Synchronous Buck MOSFET Drivers The NCP5901 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.
