Abstract
A molded inductor includes a winding having leads configured for attaching leads of the winding to pads on a package substrate, having a magnetic core with a body disposed within the winding, wherein the magnetic core has at least one mold flow enhancing feature that enhances a filling of a magnetic mold material as compared to a filling provided by a uniform cylindrical body. The magnetic mold material encases the winding and the magnetic core to form either a standalone discrete inductor component, or the magnetic component of an output filter of an integrated switching power converter module.
