DATA SHEET www.onsemi.com Synchronous Buck MOSFET Drivers NCP81166, NCP81166A The NCP81166/A 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. 2mm x 2mm DFN8 package allows for space−optimized board layout. Zero current detect feature allows for a high−efficiency solution even at light load conditions. Pre−OVP feature aids in protecting the load in the event of a short across the high−side FET. VCC UVLO ensures the MOSFETs are off when supply voltages are low. A bi−directional Enable pin provides a fault signal to the controller when a pre−OVP or UVLO fault is detected. Features • Space−Efficient 2 mm x 2mm DFN8 Thermally−Enhanced Package • VCC Range of 4.5 V to 13.
