uP1991 Datasheet 12v MOSFET Drivers

Manufacturer: uPI Semiconductor

Overview: uP1991 12V MOSFET Drivers with Output Disable for Single Phase Synchronous-Rectified Buck Converter.

Datasheet Details

The uP1991 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 capacitive load with 30ns transition time. This device combined with uPI multi-phase buck PWM controller forms a complete core voltage regulator for advanced microprocessors. The uP1991 features anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintains minimum deadtime for optim.
