Abstract
A voltage control device includes an output module and a control module. The output module provides an output current at an output terminal thereof based on a control voltage. The control module includes a comparing circuit, a capacitor, a charging circuit and a discharging circuit. The comparing circuit compares a to-be-compared voltage, which is associated at least with a to-be-controlled voltage at the output terminal of the output module, with a predetermined reference voltage to generate a comparison signal. The capacitor provides the control voltage. The charging circuit is operable to charge the capacitor based on the comparison signal. The discharging circuit is operable to discharge the capacitor based on the comparison signal.
