Abstract: Provided is a control device is for a switching voltage regulator having a switching circuit. The control device receives input and output voltages of the switching circuit and a measurement signal indicative of a current of the switching circuit. The control device has: a feedback module that detects an error signal indicative of a difference between the output voltage and a nominal voltage, and provides a control signal as a function of the error signal; a threshold-correction module that provides offset and ramp signals; and a driving-signal generation module coupled to the feedback and threshold-correction modules, which receives the measurement signal, compares the measurement signal with a threshold and, in response, provides a modulated signal for driving the switching circuit. The threshold is a function of the control, offset and ramp signals. The threshold-correction module provides the offset signal as a function of the input or output voltages.

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.
