A power architecture that uses an efficient intermediate power conversion stage between AC adaptor (and battery charger) and subsequent voltage regulators (VRs) (e.g., core VR) for processors for higher overall efficiency allowing for higher performance in a given thermal envelope and iso-system input power. Power losses from both the charger and the core VR are reduced by splitting the power as power to sustained high-power rails, and power to the rest of the platform power rails that have low residency in high-power states. The sustained high-power rails are placed under an intermediate power conversion topology which is directly powered by the adaptor. The rest of the rails along with charging of the battery are powered by the battery charger.

Techniques for battery retention are disclosed. In the illustrative embodiment, a thin polyurethane strap is used to hold a battery in place. The strap only requires a small amount of volume, allowing for a higher volume (and higher capacity) for the battery. In order to accommodate swelling, a computing device that has a battery held in place with such a strap can have an open area above the battery. The strap may have ridges to contact the battery and the component above the battery beyond the open area. If the battery swells, the ridges may be pressed down, accommodating the swelling battery.

A buck-boost converter having dual-folded bootstrap for driver metal oxide semiconductor (DrMOS) device that, in addition to the traditional bootstrap capacitors, include folded bootstrap capacitors that cross-couple inductor nodes to the two sets of DrMOS switches. The DrMOS switches can be n-type or p-type, and can be replaced with driver Gallium Nitride (DrGaN) devices.

Techniques and mechanisms for determining a delivery of power by a programmable power supply. In an embodiment, controller circuitry of a platform receives an indication that a load of the platform is to transition to a particular operational mode. Based on a power requirement of the operational mode, the controller circuitry identifies a mode of voltage regulation which is to be provided with converter circuitry of the platform. The controller circuitry signals that a programmable power supply, which is coupled to the platform, is to output a supply voltage at a level which is based on an amount of power loss associated with the mode of voltage regulation. In another embodiment, the controller circuitry identifies the mode of voltage regulation based on an amount of charge which is currently stored by a battery of the platform.

Device, method and system for programming a power supply to facilitate dynamic performance tuning

A first apparatus is disclosed, including: a detection circuitry to detect a first voltage level of reference current received from a second apparatus, where the second apparatus is to provide the reference current at a second voltage level; and a controller to negotiate a power transmission agreement with the second apparatus for transmission of power from the second apparatus to the first apparatus, based at least in part on a difference between the first voltage level and the second voltage level.

Detection of transmission medium state for power delivery

An apparatus is provided which includes: an input/output (I/O) port to be coupled to a device external to the apparatus; a battery having an output node; a voltage regulator to selectively supply power from the I/O port to the battery, to charge the battery; and a switch coupled between the I/O port and the output node, wherein the switch is to selectively allow flow of current from the device to the output node by bypassing the voltage regulator.

Supplemental power reception by bypassing voltage regulator

The present disclosure describes a number of embodiments related to devices, systems, and methods related to a plurality of displays coupled to one or more processors to display images, and a device display manager to identify a gesture made on a first display of the plurality of displays, and to cause a second display to sleep or to wake based upon the identified gesture and a current state of the second display, where the first and second displays are different displays.
