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 number of output phases of a switching power supply are controlled, to regulate its output. An under-voltage condition is responded to, by overriding the control of the output phases, forcing some or all of the phases on, depending on a detected magnitude of a change in the power supply load. Other embodiments are also described and claimed.

摘要： An improved multi-phase voltage regulator is disclosed. That voltage regulator includes a multi-phase switching signal generator for generating a plurality of out of phase switching signals. Those switching signals define a fixed duty cycle for each of a plurality of switching voltage converters. A switching mechanism is coupled to the multi-phase switching signal generator. That switching mechanism has an input for receiving a feedback voltage and includes logic for enabling and disabling the multi-phase switching signal generator.

摘要： A system and method for automatically adjusting microprocessor activity following thermal stress of a voltage regulator is disclosed. A thermal monitoring circuit determines whether the voltage regulator has exceeded a predetermined temperature. The thermal monitoring circuit may employ a temperature-sensing component such as a thermistor to determine the temperature or may derive the temperature indirectly, based on the average input (or output) current. When the over-temperature condition occurs, a signal activates the PROCHOT#, or similar, pin on a microprocessor, throttling the microprocessor clock. Where the microprocessor includes no internal power-reducing feature, the signal throttles an external clock coupled to the microprocessor. In either case, execution of the microprocessor is slowed down. At all times, the voltage regulator maintains the ability to supply continuous current to the microprocessor.

摘要： A multi-phase DC—DC converter having redundant DC—DC phases or modules. If a DC—DC phase fails, such as from a short circuit, it is decoupled from the output of the DC—DC converter. In some embodiments, the other DC—DC phases bear the burden of the extra power output. In other embodiments, additional DC—DC phases are coupled in, in response to the failure.
