Abstract: A control device for a switching voltage regulator of the buck-boost type having a switching circuit. The control device is configured to perform a current-control of the switching circuit and is formed by a filter and a loop control circuit. The filter is configured to be coupled to a resistive element of the switching circuit and to provide a filtered signal starting from a measurement signal indicative of a current flowing through the resistive element. The loop control circuit is configured to generate one or more switching control signals to drive the switching circuit, as a function of the filtered signal. The filter is configured to receive a filter control signal indicative of an actual operating mode of the switching voltage regulator. The filter is variable as a function of the filter control signal.
