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.
