    Abstract: A dedicated pin of a processor or system-on-chip (SoC) is used to indicate whether power level (e.g., charge, voltage, and/or current) of a battery falls below a threshold. The threshold can be predetermined or programmable. The battery is used to provide power to the processor and/or SoC. Upon determining that the power level of the battery falls below the threshold, the processor by-passes the conventional process of entering low performance or power mode, and directly throttles voltage and/or operating frequency of the processor. This allows the processor to continue to operate at low battery power. The fast transition (e.g., approximately 10 μS) from an active state to a low performance or power mode, in accordance with a logic level of the voltage on the dedicated pin, reduces decoupling capacitor design requirements, and makes it possible for the processor to adapt higher package power control settings (e.g., PL4).

    Abstract: A computing system may include a base portion to receive one or more first batteries, and a tablet portion having one or more electronic components and the tablet portion to receive one or more second batteries. The tablet portion may be configured to be coupled to and detached from the base portion. The computing system may also include circuitry to control a supply of voltage to one or more electronic components of the tablet portion from one or more first batteries at the base portion and from one or more second batteries at the tablet portion.

    Abstract: An on-package voltage regulation system includes a platform controller hub (PCH), a driver metal-oxide-semiconductor field-effect transistor (DRMOS) control unit, and a plurality of inductors coupled to an output node. The PCH receives a voltage feedback signal corresponding to an output voltage at the output node, and outputs a control signal based on a difference between the voltage feedback signal and a reference voltage. The DRMOS control unit includes a plurality of switch transistors and a DRMOS controller. The switch transistors are coupled to the output node through the plurality of inductors. The DRMOS controller includes logic to determine an output current based on the control signal from the PCH, and to determine a distribution of the output current through the plurality of inductors. Transistor drivers control the switch transistors to share the output current through the plurality of inductors based on the determined output current and distribution.
