摘要： A DC/DC converter includes a first switchcoupled to an input voltage and to a reference voltage. The first switch is suitable for driving a load connected to the output terminal of the DC/DC converter. The DC/DC converter includes an inductor having an intrinsic resistance and being connected to a terminal of the first switch, and a control circuit suitable for generating a driving signal of the first switch at a switching pulse. The control circuit has a first input terminal connected to the output terminal of the DC/DC converter. The DC/DC converter comprises a resistive element and a capacitor connected between the terminal of the first switch and the reference voltage. The control circuit has a second input terminal connected with the terminal in common of the capacitor and of the resistance.

摘要： A control circuit for a DC/DC converter has a linear-control loop, which receives a quantity to be controlled and a first reference quantity, and generates a modulation value. A nonlinear modulation unit is activated in presence of a variation of the quantity to be controlled higher than a preset intervention threshold and modifies in a nonlinear way the reference quantity supplied to the linear-control loop. In the case of large variation and of preset sign of the quantity to be controlled, the linear-control loop is deactivated, a signal for switching-off of the DC/DC converter is initially generated, and then a false steady-state-modulation value is supplied to the DC/DC converter.
