Claim 49:
50. 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;
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 for delivery to the semiconductor device, wherein a ratio of input voltage to output voltage of each switching power conversion circuit is at least 5;
an additional switching power conversion circuit mounted to a bottom surface of the substrate within, or substantially within, 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 semiconductor device, wherein a ratio of input voltage to output voltage of the additional switching power conversion circuit is at least 5; and
the substrate comprises 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 semiconductor device to conduct power from the additional switching power conversion circuit to the large-scale semiconductor device.
