Claim 8:
9. A method comprising:
manufacturing a voltage regulator assembly, wherein manufacturing the voltage regulator assembly comprises:
receiving a passive device integrated circuit (IC) die having one or more passive circuit elements implemented thereon;
coupling a plurality of solder balls coupled to the passive device IC die;
receiving a voltage regulator controller circuit comprising one or more circuit elements of a voltage regulator circuit;
arranging an interconnect layer between the passive device IC die and the voltage regulator controller circuit;
electrically coupling the interconnect layer to the passive device IC die by a first plurality of electrical connectors;
electrically coupling the voltage regulator controller circuit to the one or more passive circuit elements using the interconnect layer; and
electrically coupling the interconnect layer to ones of the plurality of solder balls using corresponding ones of a second plurality of electrical connectors, the second plurality of electrical connectors comprising a plurality of connecting vias passing through the passive device IC die.
