    • A driver circuit (300) provides fast settling times, slew rate control, and power efficiency, while reducing the need for large external capacitors (340). A voltage reference circuit (310) generates a voltage reference signal (Vref ). A comparator (330) compares the voltage reference signal and a driver output signal (320) and generates an output high voltage control signal. An output driver (320) includes a first (321) and a second (322) 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 (333) to the control terminal of the first switch and coupling an input signal (power down) to the control terminal of the second switch.
    • 驱动电路(300)提供快速建立时间,转换速率控制和功率效率,同时减少对大型外部电容器的需求(340)。 电压参考电路(310)产生电压参考信号(Vref)。 比较器(330)比较电压基准信号和驱动器输出信号(320),并产生输出高电压控制信号。 输出驱动器(320)包括耦合在一起的第一(321)和第二(322)开关。 第一和第二开关还被耦合以响应于将输出高电压控制信号(333)耦合到第一开关的控制端而产生驱动器输出信号,并将输入信号(掉电)耦合到控制端 第二个开关
