A driver circuit (1000) for driving functional means, such as an LED (1020-1023), a buzzer (1060), a voltage converter or an EL-lamp, and a method of operating the driver circuit are provided. The circuit includes an inductor (1030), first and second connection points for connection of a voltage source (1050), switching means (1040) which when in a first state allows an electrical current to flow from the first connection point and through the inductor to thereby charge the inductor with energy and when in a second state substantially prevents an electrical current from flowing from the first connection point to the inductor and at least two functional means, the function of which are activated when energy is discharged from the inductor to the at least two functional means.
