Abstract:
A control circuit for a switching voltage regulator is disclosed, having a charging circuit, a discharging circuit, and a charging-discharging control circuit. The charging circuit generates a charging current according to the input voltage and the output voltage of the switching voltage regulator for charging a capacitor. The discharging circuit generates a discharging current according to the output voltage of the switching voltage regulator for discharging the capacitor. The charging-discharging control circuit configures the charging circuit, the discharging circuit, and the switching voltage regulator according to the voltage of the capacitor for providing a control signal to configure the switching voltage regulator.
