onsemi NCP81151B VR12.5 Compatible MOSFET Driver

onsemi NCP81151B VR12.5 Compatible Dual MOSFET Driver provides an optimized solution to drive the gates of low and high-side power MOSFETs in a synchronous buck converter. onsemi NCP81151 Dual MOSFET Driver can drive up to 3nF load with a 25ns propagation delay and 20ns transition time.

The device delivers a low switching loss and high efficiency using adaptive anti-cross-conduction and a power-saving operation circuit. NCP81151B's UVLO function ensures the outputs are low when the supply voltage is low.
