Disclosed is a field device with a switching converter circuit. The field device having the switching converter circuit (2) and a measuring circuit (3) for determining at least one measuring variable is described and shown. The switching converter circuit (2) is supplied with electric power on the input side and the switching converter circuit (2) is connected to the measuring circuit (3) on the output side and the switching converter circuit (2) supplies the measuring circuit (3) with electric power. The problems associated with variable random interfering signals are overcome by means of the switching converter circuit in that a load circuit (5) is actuated by a load control circuit (6) so that the output-side electric load at the switching converter circuit (2) does not fall below a minimum electric load.
