| 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 compone... |
