Providing additional current capacity to a processor for a turbo mode

摘要

In one embodiment, the present invention includes a primary voltage regulator to couple a regulated voltage to a processor via a supply line. This regulator includes a multi-phase controller to provide the regulated voltage in multiple phases and to provide a maximum current output sufficient to meet a thermal design power (TDP) of the processor. In addition, an auxiliary voltage regulator may be configured to provide an excess current to the processor via the supply line for a time limited duration, e.g., based on the supply line state. Other embodiments are described and claimed.
