Abstract: A device that provides a circuit for controlling the power supply of a plurality of groups of light sources, preferably of the light-emitting diodes type, which perform a plurality of lighting functions for an automobile vehicle. The device is noteworthy in that it enables a primary output voltage and several high-voltage secondary outputs to be produced, corresponding to the power supply requirements of the various groups of light sources, with the use of a single switch-mode converter circuit.
