Abstract
A magnetic component assembly includes a circuit board having at least one layer. A first winding is provided on at least one surface of a layer of the circuit board and a further winding is provided on the same or a different surface of the circuit board. A first magnetic core is associated with the first winding to define a first magnetic component and a further magnetic core is associated with the further winding to define a further magnetic component. There is thereby provided an assembly of two or more magnetic components integrated in a single circuit board providing an efficient space saving configuration. A particular application relates to the provision of integrated magnetic components for power supplies.
