Abstract
A driver device of a plurality of light sources, in particular LEDs, includes a multi-channel current control module (20) which sets a power supply current on a respective output channel connected to at least one light source (12). At least one static configuration register (54) is connected to said current control module in which a static driving configuration corresponding to the value of the power supply current which the multi-channel current control module must set on each output channel when the driver device is in a stand alone operating mode, is pre-loaded as well as at least one dynamic configuration register (56) that acts to load a dynamic driving configuration received from a digital transmission data bus connected to an electronic control unit.
