Abstract (en)
A driver device comprises a converter circuit configured to generate and output a load current for driving an electric load and a control circuit configured to control operation of the converter circuit. The control circuit is configured to perform a functional test for testing electronic circuitry of the driver device that includes the converter circuit. The driver device may be a light driver device, preferably for proving the load current to a LED lighting device. The control circuit is configured to perform the functional test by executing a test routine for testing at least one electrical parameters of the driver device.
