NCP81063 Synchronous Buck MOSFET Drivers The NCP81063 is a high−performance dual MOSFET gate driver in a small 3 mm x 3 mm package, optimized to drive the gates of both high−side and low−side power MOSFETs in a synchronous buck converter. A zero−current detection feature allows for a high−efficiency solution even at light load conditions. 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 UVLO fault is detected. Features • Space−efficient 3 mm x 3 mm DFN8 Thermally−enhanced Package • VCC Range of 4.5 V to 13.
