The DC-DC converter includes an inductor cooperating with a first switch and a second switch operating alternately, in order to supply an output voltage of higher, equal or lower level than the level of an input voltage. The converter includes a switching control unit for the switches for determining a first switching time for the first switch and a second switching time for the second switch. The switching control unit includes a voltage-current conversion circuit for converting into current a comparison voltage, which is the difference between the output voltage and the input voltage, a first current being supplied by the conversion circuit for charging a first capacitor to a first voltage threshold to determine the first switching time and a second current being supplied by the conversion circuit for charging a second capacitor to a second voltage threshold to determine the second switching time.
