Abstract: A control device for a switching voltage regulator having a switching circuit receives a set of measurement signals including a first measurement signal indicative of an output voltage of the switching voltage regulator. A burst-mode controller is configured to monitor the output voltage with respect to a first threshold and a second threshold higher than the first threshold, and to provide, in response, a burst signal. A driving-signal generation stage is configured to provide at least one switching control signal for the switching circuit based on the burst signal and the set of measurement signals. The driving-signal generation stage has a feedback module configured to provide a control signal based on the burst signal and an error signal indicative of a difference between the first measurement signal and a reference signal.

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 circuit for decoding a pulse width modulated (PWM) signal generates an output signal switching between a first and second logic values as a function of a duty-cycle of the PWM signal. Current generating circuitry receives the PWM signal and injects a current to and sinks a current from an intermediate node as a function of the values of the PWM signal. A capacitor coupled to the intermediate node is alternatively charged and discharged by the injected and sunk currents, respectively, to generate a voltage. A comparator circuit coupled to the intermediate node compares the generated voltage to a comparison voltage and drives the logic values of the output signal as a function of the comparison.

Abstract: A control module is used to control a switching buck-boost converter that includes an inductor, a capacitor, a first top switch and a second top switch, a first bottom switch and a second bottom switch and a diode coupled to the second top switch. The control module controls the switching buck-boost converter so as to alternate: first time periods, in which the second top switch is open and cycles of charge and discharge of the inductor are carried out, during which the inductor is traversed by a current that also passes through the diode and charges the capacitor; and second time periods, in which the first and second top switches are open and the first and second bottom switches are closed so that the current in the inductor recirculates, and the capacitor is discharged by a current that flows in the load.
