Abstract
An on-package voltage regulation system includes a platform controller hub (PCH), a driver metal-oxide-semiconductor field-effect transistor (DRMOS) control unit, and a plurality of inductors coupled to an output node. The PCH receives a voltage feedback signal corresponding to an output voltage at the output node, and outputs a control signal based on a difference between the voltage feedback signal and a reference voltage. The DRMOS control unit includes a plurality of switch transistors and a DRMOS controller. The switch transistors are coupled to the output node through the plurality of inductors. The DRMOS controller includes logic to determine an output current based on the control signal from the PCH, and to determine a distribution of the output current through the plurality of inductors. Transistor drivers control the switch transistors to share the output current through the plurality of inductors based on the determined output current and distribution.
