Abstract:
A control device is provided for a switching power supply having an output that supplies an output voltage. The switching power supply includes an inductor and two changeover switches for controlling coupling of the inductor. The control device includes a first capacitor for charging with continuous current from a 0V voltage level, a second capacitor for discharging of the continuous current from a predetermined voltage level that is greater than the voltage level of a DC power supply, and a comparison circuit. The comparison circuit compares the output voltage of the switching power supply with voltage levels of the first and second capacitors and generates control signals for controlling the two changeover switches of the switching power supply. Also provided are switching power supplies having such control devices and a method for controlling a switching power supply.
