BACKGROUND

The present disclosure relates generally to information handling systems, and more particularly to configuring power delivery in information handling systems based on available power.

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

Information handling systems such as, for example, desktop computing devices, laptop/notebook computing devices, server computing devices, and/or other computing devices known in the art, are coupled to power sources that provide power to those computing devices. For example, Alternating Current/Direct Current (AC/DC) power systems such as power adapters, Power Supply Units (PSUs), and/or other AC/DC power systems known in the art may be utilized to couple a computing device to a wall outlet power source, with the AC/DC power system receiving Alternating Current (AC) power at a first power level (e.g., 110-240 volts from the wall outlet power source), and converting to Direct Current (DC) power at a second power level (e.g., 15-20 volts) that it provides to the computing device. However, AC/DC power systems are “rated” or otherwise designed to provide particular amounts of power (e.g., 50 watts, 100 watts, etc.), which can raise some issues.

For example, computing devices typically include a circuit board that connects to the AC/DC power system and that includes analog power scaling circuit(s) that are configured to convert the DC power that is received from the AC/DC power system at the second power level (e.g., 15-20 volts) to DC power at a third power level (e.g., 1.2 volts) for use by a processing system and/or other devices on the circuit board. In conventional computing devices, the circuit board and its analog power scaling circuit(s) are designed based on the rated amount of power of the AC/DC power system that will be used with those computing devices. However, users may connect different AC/DC power system with different capabilities to their computing devices during its lifetime, including AC/DC power systems with a power rating for which the circuit board and its analog power scaling circuit(s) were not designed. In situations in which the AC/DC power system connected to the computing device is rated for an amount of power that is greater than the power amount that the circuit board and its analog power scaling circuit(s) are designed for, any additional power that is over the power the circuit board and its analog power scaling circuit(s) are designed for will not be used by the computing device, resulting in inefficient use of that AC/DC power system. In situations in which the AC/DC power system connected to the computing device is rated for an amount of power that is less than the power amount that the circuit board and its analog power scaling circuit(s) are designed for, the circuit board and its analog power scaling circuit(s) may draw too much power from that AC/DC power system, resulting in an unstable computing device that may shut down due to lack of power.

Some computing devices attempt to address the possibility of being connected to different AC/DC power systems rated for different amounts of power by designing their circuit board and its analog power scaling circuit(s) for two different rated power amounts. For example, the circuit board and its analog power scaling circuit(s) in a computing device may be designed for use with both a AC/DC power system rated for 50 watts of power, and a AC/DC power system rating for 100 watts of power. However, such solutions are still limited to operating properly with particular AC/DC power systems, and the use of an AC/DC power system that does not include the particular power rating for which the circuit board and its analog power scaling circuit(s) were designed (e.g., 75 watts)) will still produce the issues discussed above.

Accordingly, it would be desirable to provide power-availability-based power delivery configuration system that addresses the issues discussed above.

SUMMARY

According to one embodiment, an Information Handling System (IHS) includes a controller processing system; and a controller memory system that is coupled to the controller processing system and that includes instructions that, when executed by the controller processing system, cause the controller processing system to provide a power scaling controller engine that is configured to: identify a power amount available from a power system; determine, based on the power amount available from the power system, power delivery settings for an adjustable power scaling circuit that is coupled to the power system and a device, and that is configured to convert power received from the power system from a first power level to a second power level; and configure, using the power delivery settings, the adjustable power scaling circuit.
