Abstract
An electronic ballast arrangement for a discharge lamp is provided. The electronic ballast arrangement includes an electronic ballast for a discharge lamp with a control application specific integrated circuit, the control application specific integrated circuit having a control input, which is characterized by the fact that the potential present across it sets the operating frequency of the control ASIC when driving the discharge lamp; and a switch; wherein the electronic ballast is connected to the switch, with different switching positions of the switch determining different potentials which are present at the control input, in order to thus set the operating frequency of the control application specific integrated circuit via the switch.
