A method and device of controlling a dimmable driver (201), and a dimmable driver (201). The output voltage of the dimmable driver is increased when the dimmable driver (201)is in a condition of light load or in a low dimming level(101). The output voltage of the dimmable driver(201) can be maintained above the minimum voltage required for good constant current control in the illuminating device(202) when the dimmable driver(201) is in a condition of light load. Therefore, accurate dimming can be realized and flicker of the illuminating device (202) can be eliminated.
