Summary:A driver circuit provides fast settling times, slew rate control, and power efficiency, while reducing the need for large external capacitors. A voltage reference circuit generates a voltage reference signal. A comparator compares the voltage reference signal and a driver output signal and generates an output high voltage control signal. An output driver includes a first and a second switch that are coupled together. The first and second switches are further coupled to generate the driver output signal in response to coupling the output high voltage control signal to the control terminal of the first switch and coupling an input signal to the control terminal of the second switch.
