Abstract
An embodiment of the present disclosure relates to a power supply interface comprising: a converter delivering a first DC voltage; a resistor connected between the converter and an output terminal of the interface delivering a second DC voltage; a first circuit delivering a second signal representative of a difference between the second DC voltage and a voltage threshold when a first signal is in a first state, and at a default value otherwise; a second circuit delivering a third signal representative of a value of a current in first resistor multiplied by a gain of the third circuit, and modifying the gain based on the second signal; and a third circuit configured to deliver a signal for controlling the converter based at least on the third signal.
