    • The present invention discloses a multifunctional driver controller capable to drive one or more voltage-controlled devices or current-controlled devices. According to one embodiment, the multifunctional driver controller comprises a selection unit receiving a control signal, one of a first reference voltage and a second reference voltage, the selection unit selecting either one of the first reference voltage and the second reference voltage per the control signal, and a control circuit receiving a reference voltage from the selection unit and a feedback signal from a load being driven by a controlled analog signal from the control circuit, wherein the controlled analog signal is either a controlled voltage signal or a controlled current signal, the control circuit compares the reference voltage with the feedback signal and adjusts the controlled analog signal in reference to a difference between the reference voltage and the feedback signal until the feedback signal converges to the reference voltage.
    • 本发明公开了一种能够驱动一个或多个压控装置或电流控制装置的多功能驱动控制器。 根据一个实施例,多功能驱动器控制器包括选择单元,其接收控制信号,第一参考电压和第二参考电压中的一个,选择单元根据控制信号选择第一参考电压和第二参考电压中的任一个 以及从所述选择单元接收参考电压的控制电路和来自所述控制电路的受控模拟信号驱动的负载的反馈信号,其中所述受控模拟​​信号是受控电压信号或受控电流信号, 控制电路将参考电压与反馈信号进行比较,并参考参考电压和反馈信号之间的差值调整受控模拟信号,直到反馈信号收敛到参考电压。
