Abstract
An integrated circuit system includes a substrate of an electrical insulating material having a surface. Mounted on the surface of the substrate is an IC, a semiconductor piece having therein a circuit, such as a microprocessor, having a plurality of functional blocks. Also mounted on the substrate are a plurality of power supply chips. Each of the power supply chips is connected through conductors and vias in the substrate to a separate functional block on the IC semiconductor piece. Each of the power supply chips forms part of a circuit, such as a DC-DC converter, which is capable of reducing a voltage supplied thereto to a lower voltage suitable for the particular functional block to which the particular power supply chip is connected. Thus, a single relatively large voltage fed to the power supply chips through conductors on the substrate is reduced by each power supply chip to a lower voltage suitable for the particular functional block of the IC semiconductor piece.
