Overview

NCP81146 VR12.5 Compatible Synchronous Buck MOSFET Drivers 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 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.
