Patent number: 11449127Abstract: Peak power setting circuitry is provided to set a peak power value for an integrated circuit device. A power supply interface is to receive a value to estimate a peak power capacity of a power supply serving the integrated circuit device and processing circuitry is provided to calculate an approximate peak power for the integrated circuit device. A peak power for the integrated circuit device is determined by increasing the approximate peak power depending on an amount by which the integrated circuit device power is reduced in response to assertion of a throttling signal.Type: GrantFiled: September 28, 2017Date of Patent: September 20, 2022Assignee: Intel CorporationInventors: Eugene Gorbatov, Alexander Uan-Zo-Li, Chee Lim Nge, James Hermerding, II, Zhongsheng Wang

Patent number: 11429172Abstract: A power supply architecture combines the benefits of a traditional single stage power delivery, when there are no additional power losses in the integrated VR with low VID and low CPU losses of FIVR (fully integrated voltage regulator) and D-LVR (digital linear voltage regulator). The D-LVR is not in series with the main power flow, but in parallel. By placing the digital-LVR in parallel to a primary VR (e.g., motherboard VR), the CPU VID is lowered and the processor core power consumption is lowered. The power supply architecture reduces the guard band for input power supply level, thereby reducing the overall power consumption because the motherboard VR specifications can be relaxed, saving cost and power. The power supply architecture drastically increases the CPU performance at a small extra cost for the silicon and low complexity of tuning.Type: GrantFiled: January 6, 2020Date of Patent: August 30, 2022Assignee: Intel CorporationInventors: Alexander Uan-Zo-Li, Eugene Gorbatov, Harish Krishnamurthy, Alexander Lyakhov, Patrick Leung, Stephen Gunther, Arik Gihon, Khondker Ahmed, Philip Lehwalder, Sameer Shekhar, Vishram Pandit, Nimrod Angel, Michael Zelikson

Patent number: 11342775Abstract: Techniques and mechanisms for supplementing power delivery with a battery. In an embodiment, a voltage is provided at a first node with the battery to power a load circuit. A charger is coupled between the first node and a second node, wherein a capacitor is coupled to provide charge to the charger via the second node. In response to detecting a transition of the voltage below a threshold voltage level, controller logic operates switch circuitry of the charger to provide charge from the capacitor. Such operation maintains the voltage in a range of voltage levels which are each above a minimum voltage level required by the load. At least a portion of the range is below the threshold voltage level. In some embodiments, another voltage at the second node provides a basis for generating a control signal to throttle an operation of the load circuit.Type: GrantFiled: March 27, 2020Date of Patent: May 24, 2022Assignee: Intel CorporationInventors: Tod Schiff, Teal Hand, Alexander Uan-Zo-Li

Publication number: 20220091656Abstract: A driver (e.g., a firmware or software) that improves the performance of the system-on-chip (SoC) in battery mode. The driver is a Peak Power Manager (PPM) which allows drastically higher SoC peak power limit levels (and thus higher Turbo performance) in battery mode. The PPM sets the Vth threshold voltage (the voltage level at which the platform will throttle the SoC) in such a way as to prevent the system from unexpected shutdown (or black screening). The PPM calculates the Psoc,pk SoC Peak Power Limit (e.g., PL4), according to the threshold voltage (Vth). These are two dependent parameters, if one is set, the other can be calculated. The scheme by the PPM is used to optimally set one parameter (Vth) based on the system parameters, and the history of the operation.Type: ApplicationFiled: September 23, 2020Publication date: March 24, 2022Applicant: Intel CorporationInventors: Chee Lim Nge, Alexander Uan-Zo-li, Zhongsheng Wang, James Hermerding, II, Caren Magi

Patent number: 11275663Abstract: 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 ?S) 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).Type: GrantFiled: June 8, 2020Date of Patent: March 15, 2022Assignee: Intel CorporationInventors: Alexander Gendler, Nimrod Angel, Ameya Ambardekar, Sapumal Wijeratne, Vikas Vij, Tod Schiff, Alexander Uan-Zo-Li

Patent number: 10802557Abstract: Systems, apparatuses and methods may provide for technology that supplements a battery coupled to a processor configuration with stored energy from a charger input, wherein the battery is supplemented with the stored energy in response to an increased power demand on the battery. The technology may also initiate one or more throttle operations in the processor configuration if the increased power demand does not end before the stored energy is depleted. If the increased power demand ends before the stored energy is depleted, the one or more throttle operations may be bypassed. The increased power demand may correspond to a system voltage being below a voltage threshold, a battery current being above a current threshold, and so forth.Type: GrantFiled: June 28, 2018Date of Patent: October 13, 2020Assignee: Intel CorporationInventor: Alexander Uan-Zo-li
