UP6281, 12V MOSFET Drivers

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 combined with uPI multi-phase buck PWM controller forms a complete core voltag

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 high-impedance at PWM pin, preventing rapid output capacitor discharge during system shutd
