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.
