Abstract: A power converter circuit included in a computer system that regulated a power supply voltage used by other circuits in the computer system. The power converter includes a primary control circuit that selectively activates multiple phase circuits coupled to respective driver circuits, which are coupled to a power supply node via respective inductors. Some of the driver circuits are located on a separate integrated circuit from the primary control circuit and the multiple phase circuits.
