Abstract: In an embodiment a control device includes a first input configured to receive a measurement signal representative of an output voltage of a switching circuit of a voltage regulator, a state determination block coupled to the first input and configured to generate a signal of actual operating condition of the voltage regulator and a driving signals generation module configured to generate at least one switching command signal for the switching circuit from an error signal representative of a difference between the output voltage and a nominal voltage, wherein the driving signals generation module includes an error-compensation circuit having a transfer function and configured to generate a control signal from the error signal and the actual operating condition signal, the control signal being a function of the actual operating condition.

Abstract: A controller for a buck-boost switching converter, which includes an inductor and a shunt resistor and is coupled to a load which draws a load current, includes a control circuit which performs charge and discharge cycles of the inductor. A first comparator stage generates a first signal which is indicative of a direction of the resistor current during the charge and discharge cycles. A low-pass filtering circuit generates a filtered electrical quantity based on a voltage on the shunt resistor during the charge and discharge cycles. A second comparator stage generates a second signal indicative of a comparison between the filtered electrical quantity and a reference electrical quantity. A detection stage detects the occurrence of an overcurrent in the load based on the second signal.
