Abstract: Techniques and devices related to power adapters for mobile devices and, in particular, small form factor power adapters that allow a voltage droop during a power pulse exceeding a maximum output of the power adapter are discussed. For example, a small form factor and low voltage power adapter may include an adapter output power protection control that limits an output of the power adapter in response to a power pulse exceeding a maximum output of the power adapter.

Abstract: A method and apparatus for adjusting the charge for a battery under a power sharing arrangement is disclosed. In one embodiment, the method comprises determining if power output capacity of an alternating current (AC) adapter is less than or greater than a system power requirement for a system that receives power from the AC adapter and a battery, determining a charge current for charging the battery from the AC adapter, based on a voltage range of the battery, the current charge being less than excess current available from the AC adapter in view of determining that the power output capacity of the AC adapter is greater than the system power requirement, and controlling a battery charger to charge the battery with the charge current by specifying the charge current to the battery charger if the power output capacity of the AC adapter is greater than the system power requirement.

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.
