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.
