NCP81146: VR12.5 Buck MOSFET Driver
The NCP81146 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 guarantees the outputs are low when supply voltage is low
特性- Faster rise and fall times
- Adaptive anti-cross-conduction circuit
- Integrated bootstrap diode
- Pre OV function
- ZCD detect
- Floating top driver accommodates boost voltages of up to 35V
- Output disable control turns off both MOSFETs
- Under-voltage lockout
- Power saving operation under light load conditions
