Abstract

A switched-mode power supply includes at least one capacitor (9) and a transformer having a plurality of windings (12, 17). Advantageously a capacitor (9) is integrated in the transformer by way of at least one multi-layer foil winding (12). This foil winding (12) of the transformer consists of a plurality of planar conductive electrodes (1, 2, 3, 4, 5, 6) which, alternately with an insulating dielectric foil, are stacked onto each other to form an electrode stack.
