1. An integrated device for driving a lighting load, the integrated device comprising:

  • a first memory element, configured to store a nominal duty-cycle at a nominal supply voltage;

    an actual voltage acquisition element, configured to detect an actual supply voltage;

    a processing unit, coupled to the first memory element and to the actual voltage acquisition element, configured to calculate a voltage compensated duty-cycle; and

    a driver unit, coupled to the processing unit and configured to be supplied according to the voltage compensated duty-cycle.
