Abstract
A coupled inductor topology for a thin-film magnetic core power inductor that enables efficient integrated power conversion. Coupled magnetic core inductors with interleaved windings inductors comprise magnetic films and partially or fully interleaved conductors. Methods described herein are suitable for integration into monolithic, chip stacking fabrication or other traditional semiconductor device fabrication techniques and equipment. Soft ferromagnetic materials exhibiting high permeability and low coercivity are deposited using thin-film techniques. A plurality of electrical conductors surround at least one ferromagnetic core giving rise to two or more windings. Windings are coupled to one another through magnetic core(s). Windings are used to control permeability, inductance and magnetic saturation, finding particular utility in high magnetic flux applications.
