uP1991S - 12V MOSFET Drivers

Key Features

  • The uP1991S is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs in a synchronous-rectified 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 micro-processors. The uP1991S features anti-shoot-through protection that prevents cross-conduction of the external MOSFET while maintains minimum deadtime for o.

uP1991S 12V MOSFET Drivers with Output Disable for Single Phase Synchronous-Rectified Buck Converter General Description Features The uP1991S is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs in a synchronous-rectified 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 micro-processors. The uP1991S 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.
