Datasheet Summary
12V MOSFET Drivers with Output Disable for Single Phase Synchronous-Rectified Buck Converter
General Description
The uP6281 is a dual, high voltage MOSFET driver optimized for driving two N-Channel MOSFETs in a synchronousrectified buck converter. Each driver is capable of driving a 5000pF load with 30ns transition time. This device bined with uPI multi-phase buck PWM controller forms a plete core voltage regulator for advanced micro-processors. The uP6281 Features adaptive anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintains minimum deadtime for optimized efficiency. Both gate drives are turned off by pulling low OD# pin or...
