Product Overview
NCP81151: MOSFET Driver, VR12.5 Compatible Synchronous Buck
For complete documentation, see the data sheet
Product Description
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.
The UVLO function guarantees the outputs are low when the supply voltage is low.
