Abstract
An operating device for operation of at least one illuminant, such as one or more LEDs, includes first and second converters and first and second logic circuits. The first converter is supplied directly or indirectly with mains voltage, with a first reference potential. The second converter is galvanically isolated from the first converter, with a second reference potential for supplying a load circuit with the illuminant. The first logic circuit is for controlling the first converter, and the second logic circuit is for controlling the second converter. The first logic circuit and the second logic circuit are connected to one another, with potential isolation, via an interface.
