Abstract
The magnetic device consists of a planar winding board, which contains the windings for both the inductor and the transformer. Thus, this invention centers on integrating the windings of multiple magnetic devices, not integrating the cores. By connecting the transformer secondary winding directly to the output inductor winding without using any intermediate headers and/or termination pins or conductive copper traces, both electrical path and the termination resistance will be minimized. Furthermore, the number of headers or termination pins required will also be reduced, which helps to not only alleviate the issue associated with co-planarity of the termination pins, but also reduce the cost of the material and manufacturing.
