Description

The NCP81062 is a high-performance MOSFET gate driver in a 3 mm x 3 mm packaged, optimized to drive the gates of both high-side and low-side power MOSFETs in a synchronous buck converter. 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.
