NCP81145: VR12.5 Buck MOSFET Driver
The NCP81145 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 systems.
The UVLO function guarantees the outputs are low when the supply voltage is low.
Features- Faster rise and fall times
- Adaptive anti-cross-conduction circuit
- Zero cross detection function
- Output disable control turns off both MOSFETs
- Undervoltage lockout
- Power saving operation under light load conditions
