Hot-selling and scarce NCP81166AMNTBG Synchronous Buck MOSFET Drivers DFN8 spot stock

Product Descriptions

The NCP81166/A is a high performance dual MOSFET gate driveroptimized to drive the gates of both high−side and low−side powerMOSFETs in a  synchronous buck converter. 2mm x 2mm DFN8package allows for space−optimized board layout .

Zero current detect feature allows for a high−efficiency solutioneven at light load conditions . Pre−OVP feature aids in protecting theload in the event of a short across the high−side FET. _V CC UVLOensures  the  MOSFETs  are  off when  supply  voltages  are  low.  Abi−directional Enable pin provides a fault signal to the controllerwhen a pre−OVP or UVLO fault is detected .
