uP1991 - 12V MOSFET Drivers

Key Features

  • 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.

uP1991 12V MOSFET Drivers with Output Disable for Single Phase Synchronous-Rectified Buck Converter General Description Features 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 optimized efficiency. This part has integrated bootstrap switch to help minimize the external component count.
