    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.

    摘要: A system may include a voltage controller to provide a control signal, a voltage converter to receive the control signal and to change a value of an output voltage in response to the control signal, and an evaluation circuit to determine that a threshold associated with a pulse width of the control signal has been satisfied and to change an electrical value on which a frequency of the control signal is based if the threshold has been satisfied. The voltage controller may increase the frequency of the control signal in response to the changed electrical value. The increase in frequency may be continuous and may begin at start-up.
