    Abstract: In a device (1) for driving LEDs (7) with variable light intensity, a supply stage (9) has a first operating mode, in which a controlled supply current (I out ) is generated, and a second operating mode, in which a controlled supply voltage (V out ) is generated. A LED (7) is connected to the supply stage (9), receives the controlled supply current or voltage, and has a turning-on threshold voltage higher than the controlled supply voltage (V out ). A current sensor (11) generates a current-feedback signal (V1 fb ) that is correlated to the current flowing in the LED (7) and is supplied to the supply stage (9) in the first operating mode. An intensity-control stage (13, 14) generates a mode-control signal (V2 fb ) that is sent to the supply stage (9) and controls sequential switching between the first and the second operating modes of the supply stage (9).

    Abstract: A capacitor for sensing the substrate voltage is efficiently and economically realized simply by isolating a portion or segment of the metal layer that normally covers the heavily doped perimetral region of electric field equalization and, in correspondence of such a metal segment isolated by the remaining portion, by not removing preventively the isolation dielectric layer of silicon oxide from the surface of the semiconductor substrate, as it is normally done on the remaining portion of the perimetral edge region before depositing the metal. The unremoved layer of isolated silicon oxide becomes the dielectric layer of the so constituted capacitor, a plate of which is the heavily doped perimetral region that is electrically connected to the substrate (drain or collector region) while the other plate is constituted by the segment of metal, isolated from the remaining metal layer defined directly over the heavily doped perimetral region.

    Abstract: A device for recognizing the power supply of discharge lamps comprises an output block for the power supplying of the lamp and a power-factor correction block 20 for correcting the power factor on the basis of a given conduction time. A control circuit, such as a microcontroller, which is sensitive to the supply voltage of the lamp, is able to detect the striking voltage of the lamp and to obtain a first recognition of the power supply of the lamp as a function of the striking voltage, likewise estimating the conduction time for the correction of the power factor as a function of the power supply corresponding to the aforesaid first recognition. The control circuit is configured for measuring the conduction time for the correction of the power factor effectively applied to the lamp and comparing the estimated conduction time for the correction of the power factor with the measured one. Consequently:
    - i) if the estimated conduction time and the measured conduction time are consistent with one another, the control circuit recognizes the power supply as the one corresponding to the first recognition; and
    - ii) if the estimated conduction time and the measured conduction time are not consistent with one another, the control circuit recognizes the power supply as the one corresponding to the conduction time measured.
