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.

Abstract: The present disclosure relates to an interface comprising: a terminal for delivering a DC voltage; a comparator for delivering a first signal representative of a comparison of the DC voltage with a high threshold; a comparator for delivering a second signal representative of a comparison of the DC voltage with a low threshold; and a circuit configured to: deliver successive pairs of values of high and low thresholds for a time period after the DC voltage crosses a first value of the low threshold; modify successive pairs of values of the thresholds based on the first and second signals to determine values of thresholds surrounding the DC voltage; and determining a current value of the DC voltage based on the values of thresholds surrounding the DC voltage.

Abstract: A first terminal receives a first DC voltage. A switch selectively couples the first terminal to a second terminal providing an output. A control circuit selectively actuates the switch in response to a comparison of the first DC voltage to a second DC voltage. A low-dropout (LDO) linear voltage regulator, connected between the first and third terminals, operates to provide the second DC voltage from the first DC voltage.

Abstract: The present disclosure concerns a device comprising: a voltage converter supplying, from a first DC voltage, a second DC voltage on an output terminal of the converter having a current value determined by a third voltage on a control terminal of the converter; a circuit configured, when a set point value of the second voltage switches from a first to a second set point value smaller than the first value, to generate a ramp signal successively representative of the first value, of a plurality of decreasing intermediate values between the first and second values, and of the second value; and an amplifier supplying a first signal representative of a difference between the ramp signal and a signal representative of the current value of the second voltage, the third voltage being determined by the first signal.
