Claim 59:
60. An apparatus comprising:
a substrate having a plurality of interface connections connected to at least one surface of the substrate;
a large-scale semiconductor device mounted to a top surface of the substrate, the large-scale semiconductor device having a high-power rail for receiving input power at a first voltage;
one or more switching power conversion circuits mounted to the top surface of the substrate laterally adjacent to one or more sides of the large-scale semiconductor device, each switching power conversion circuit including at least one switch and an inductive component and being constructed and arranged to convert power from an input at an input voltage to an output at an output voltage, wherein the input voltage is greater than the output voltage;
an additional switching power conversion circuit mounted on a bottom surface of the substrate within at least a portion of a footprint of the large-scale semiconductor device, the additional switching power conversion circuit including at least one switch and an inductive component and being constructed and arranged to convert power from an input at an input voltage to an output at an output voltage for delivery to the high-power rail of the large-scale semiconductor device at the first voltage, wherein the input voltage is greater than the output voltage of the additional switching power conversion circuit;
the substrate including a plurality of vertical power connections extending vertically through the substrate from the top surface to the bottom surface, the vertical power connections being arranged with alternating polarities within a footprint of the large-scale semiconductor device to conduct power from the additional switching power conversion circuit to the high-power rail of the large-scale semiconductor device.
