NCP81151, VR12.5 Compatible Synchronous Buck MOSFET Driver
Pin No.
1 Symbol BST Description Floating bootstrap supply pin for high side gate driver.
Connect the bootstrap capacitor between this pin and the SW pin.
2 PWM Control input.
The PWM signal has three distinctive states: Low = Low Side FET Enabled, Mid = Diode Emulation Enabled, High = High
NCP81151 VR12.5 Compatible Synchronous Buck MOSFET Driver The NCP81151 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 systems.
