    Abstract: A protection device is provided for protecting a switching device that is able to control a current through an inductive load which is subject to a supply voltage, by switching a first and a second terminal of the inductive load to the respective pole of the supply voltage. The switching device is under control of a switching control device. The switching control device operates based on a predetermined algorithm. The switching device also includes flyback body diodes. The protection device includes measuring means for measuring a voltage level on a terminal of the load, and decision means for making a decision on switching the first terminal of the load if the measured voltage level exceeds the supply voltage. The protection device also includes instructing means for instructing the switching control device based on the decision for switching a first terminal of the load.

    Abstract: The invention relates to a DC/DC converter or power supply with a switched-mode regulator (2), said regulator (2) being provided or associated to a feedback comparator (1) of a feedback voltage (Vact) for improving the stability of the output signal. It is further provided or associated to a means (3, D) for adding an offset voltage (Voff) to the feedback voltage (Vact) during at least one phase (null1) of the switched-mode regulator (2) or at least a portion thereof.
