Abstract

A power excursion warning system includes a power system having a first slew rate. A powered component is coupled to the power system. The powered component voltage regulator has a second slew rate that is greater than the first slew rate. A powered component voltage regulator is coupled to the powered component and operable to convert a first voltage received from the power system to a second voltage that is supplied to the powered component. A power excursion warning device is coupled to the powered component voltage regulator and operable to receive a signal from the powered component voltage regulator that is associated with the second slew rate, determine that the signal indicates a power excursion that will result in the power system operating outside a predetermined range, and produce a warning signal indicative of the power excursion.

Claims (33)

1. A power excursion warning system, comprising:

a power system having a first slew rate;

a powered component that is coupled to the power system that that has a second slew rate that is greater than the first slew rate;

a powered component voltage regulator coupled to the powered component and operable to convert a first voltage received from the power system to a second voltage that is supplied to the powered component; and

a power excursion warning device coupled to the powered component voltage regulator and operable to receive a power system output signal from the power system, receive a signal from the powered component voltage regulator that is associated with the second slew rate, determine that the signal from the powered component voltage regulator and the power system output signal indicate a power excursion that will result in the power system operating outside a predetermined range, and produce a warning signal indicative of the power excursion.

2. The power excursion system of claim 1 , wherein the powered component is a processor and the powered component voltage regulator is a processor voltage regulator that converts a system voltage provided by the power system to a processor voltage and supplies the processor voltage to the processor.

3. The power excursion system of claim 1 , wherein the power system includes a power supply unit (PSU) and the power system output signal includes a PSU output current.

4. The power excursion system of claim 1 , wherein the power system includes a system level current monitor and the power system output signal includes a current detected by the system level current monitor.

5. The power excursion system of claim 1 , wherein the warning signal is provided to the power system, and wherein the power system is operable to perform at least one power system action in response to receiving the warning signal.

6. The power excursion system of claim 1 , wherein the warning signal is provided to the powered component, and wherein the powered component is operable to perform at least one throttling action in response to receiving the warning signal.

7. An information handling system (IHS), comprising:

a processor having a processor slew rate;

a memory coupled to the processor;

a processor voltage regulator coupled to the processor and operable to convert a first voltage to a second voltage and supply the second voltage to the processor; and

a power excursion warning device coupled to the processor voltage regulator, wherein the power excursion warning device is operable to receive a power system output signal from a power system having a power system slew rate that is less than the processor slew rate, receive a signal from the processor voltage regulator that is associated with the processor slew rate, determine that the signal from the processor voltage regulator and the power system output signal indicates a power excursion that will result in the power system operating outside a predetermined range, and produce a warning signal indicative of the power excursion.

8. The IHS of claim 7 , wherein the processor voltage regulator is operable to receive the first voltage from a system voltage regulator that converts and supplies voltage to the IHS.

9. The IHS of claim 7 , wherein the power system includes a power supply unit (PSU) and the power system output signal includes a PSU output current.

10. The IHS of claim 7 , wherein the power system includes a system level current monitor and the power system output signal includes a current detected by the system level current monitor.

11. The IHS of claim 7 , wherein the warning signal is provided to the power system, and wherein the power system is operable to perform at least one power system action in response to receiving the warning signal.

12. The IHS of claim 7 , wherein the warning signal is provided to the processor, and wherein the processor is operable to perform at least one throttling action in response to receiving the warning signal.

13. The IHS of claim 7 , wherein the power excursion warning device includes a register for tracking a number of times the power excursion warning device determines that the signal from the processor voltage regulator and the power system output signal indicate a power excursion that will result in the power system operating outside a predetermined range, and wherein the warning signal is produced in response to the number of times reaching a predetermined number.

14. A method for powering a system, comprising:

receiving power from a power system having a first slew rate;

converting the power from a first voltage to a second voltage using a processor voltage regulator;

supplying the second voltage from the processor voltage regulator to a processor having a second slew rate that is greater than the first slew rate;

receiving a power system output signal from the power system;

receiving a signal from the processor voltage regulator that is associated with the second slew rate;

determining that the signal from the processor voltage regulator and the power system output signal indicate a power excursion that will result in the power system operating outside a predetermined range; and

producing a warning signal indicative of the power excursion.

15. The method of claim 14 , wherein the power system includes a power supply unit (PSU) and the power system output signal includes a PSU output current.

16. The method of claim 14 , wherein the power system includes a system level current monitor and the power system output signal includes a current detected by the system level current monitor.

17. The method of claim 14 , wherein the warning signal is provided to the power system and, in response, the power system performs at least one power system action.

18. The method of claim 14 , wherein the warning signal is provided to the processor and, in response, the processor performs at least one throttling action.
