Cooling device for an inductor winding

A printed circuit board assembly comprising:

• a printed circuit board having an upper side and a lower side;
• an inductor assembly arranged on the upper side of the printed circuit board, the inductor assembly comprising a magnetic core and a multi-turn winding wound around the magnetic core, the magnetic core having a window area, wherein inner winding sections of the multi-turn winding are arranged in the window area;
• a heat sink arranged on the lower side of the printed circuit board;
• and
• at least one heat conducting element comprising:
• a first section that is thermally coupled to the heat sink;
• and
• a second section that extends vertically from the first section through the printed circuit board into the window area of the magnetic core.
