Claim 14:
15. An apparatus comprising:
an integrated circuit having a plurality of functional circuit blocks implemented thereon;
a voltage regulator assembly coupled to the integrated circuit, the voltage regulator assembly including:
a passive device integrated circuit (IC) die coupled to the integrated circuit, the passive device IC die having one or more passive circuit components implemented thereon and further including a plurality of solder balls;
a voltage regulator controller circuit having one or more components of a voltage regulator circuit; and
an interconnect layer disposed between the passive device IC die and the voltage regulator controller circuit, wherein the voltage regulator circuit is electrically coupled to the passive device IC die by the interconnect layer, and wherein the passive device IC die is further coupled to the integrated circuit through a plurality of electrical connectors extending through the passive device IC die from the interconnect layer to one or more corresponding ones of the plurality of solder balls.
