Abstract
An inductive element including a magnetic core with a section received in a central opening defined in each of the layers in a multilayer circuit board. A primary winding, an auxiliary winding, and a secondary winding are each realized in conductive coils located on a plurality of layers in the circuit board. The secondary winding is separated from the other windings by a relatively-thick dielectric layer. Other dielectric layers separate each of the layers with the coils. EMI shields are provided on other layers. The coils are located in a central region of each layer so as to provide an adequate safety margin from the side edges of the inductive element.
