Abstract: A DC voltage converter produces an output voltage (VS) at an output terminal from an energy source. The DC voltage convert includes a selector switch includes a first input coupled to the energy source, a second input coupled to a ground, and an output coupled to a first terminal of an inductor. A second terminal is coupled to the output terminal of the converter and a capacitor is coupled between the output terminal and the ground. A regulator produces a control signal as a function of a result of a comparison of the output voltage with a reference voltage. A control circuit couples the output of the selector switch to the first or second input of the selector switch, as a function of the control signal. The converter may also include a means of inhibition adapted to inhibiting the control circuit when a current flowing in the inductor gets cancelled.
