NCP81258H中文资料MOSFET Driver, VR12 Compatible, Synchronous Buck数据手册ONSEMI规格书

描述 Description

The NCP81258H 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 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.
