摘要： Methods and systems are disclosed that may be employed to enable multi-phase voltage regulator (VR) system calibration during the development phase of a multi-phase VR system so as to meet defined accuracy targets and, in one example, to avoid the need for system level calibration in a production environment. The disclosed systems and methods may be further implemented to enable use of multiple sources for and types of integrated power stages (IPstages) in a common multi-phase VR system configuration while still achieving the required current sense accuracy, thus reducing or substantially eliminating continuity of supply (COS) concerns.

摘要： Systems and methods are disclosed that provide static phase shedding techniques to improve the efficiency of multi-phase voltage regulators within information handling systems by selecting the number of active phases for the multi-phase voltage regulators using circuit identifiers (IDs) for circuitry configured to be powered by the multi-phase voltage regulators, such as central processing units (CPUs). In one embodiment, processor identifier information related to installed CPUs is used to control the voltage regulator (VR) phase number to provide static phase shedding. This VR control can be implemented in a variety of ways, including the use of conventional analog multi-phase VR controllers and/or digital VR controllers. Dynamic phase shedding can also be used in conjunction with this static phase shedding to further reduce the number of active phases when a processor operates in a low power mode.

摘要： An information handling system (IHS) is disclosed providing a power supply operable to provide an output current to the IHS during power initiation. The IHS may also include a first power component associated with a first power stage wherein the first power stage may have a first current threshold. Furthermore, the IHS may include a power control logic coupled to the power supply and the first power component. As such, the power control logic may be operable to communicate the first power stage to the power supply, and if the output current does not exceed the first current threshold during the first power stage, the power control logic may be operable to communicate a second power stage having a second current threshold to the power supply.

摘要： A technique is disclosed for more fully utilizing the full voltage range of a battery driven battery output voltage when the battery output voltage is provided through voltage regulation circuitry. More particularly, when the battery output voltage drops to a level that is insufficient to support the desired output of the voltage regulation circuitry, the battery output voltage may be coupled to the voltage output in a manner bypassing at least a portion of the voltage regulation circuitry. In this manner additional voltage range of the battery output voltage may be utilized while still maintaining an output voltage within a desired output voltage range. In one embodiment, such a technique may be utilized in an uninterruptible power supply system.

摘要： A method and system are disclosed for improving the efficiency of a battery supplied power supply system. More particularly, a method and system is provided for improving the voltage regulation efficiency for a system in which the input voltage that is to be regulated may vary widely. In the techniques disclosed, the voltage supply that is utilized for the drive control circuitry of the voltage regulators is varied in relation to variations in the input voltage. Thus in one embodiment, the voltage supply that is utilized for the circuitry that drives a control terminal of the output transistor of the regulation circuitry may be varied in relation to variations in the input voltage. For example, an inverse relationship may be established between the input voltage level and the voltage level that is used for the gate drive circuitry that controls the gates of regulator output transistors.
