Description

The NCP81258 is a high−performance dual MOSFET gate driver in a small 2 mm x 2 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 UVLOensures 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.
