Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for providing a charger capable of adaptively handling a range of power inputs. The charger can selectively activate different control switches within the charger in order to more efficiently use current supplied to the charger. When a low power input is provided to the charger, the charger can reduce the number of active control switches being used to provide a voltage output from the charger. In this way, the capacitance required to toggle the control switches can be reduced. When a high power input is provided to the charger, the number of active control switches can be increased in order to increase a total amount of charge that can be provided from the charger, thereby reducing charge times for batteries.

Abstract translation: 本文讨论的实施例涉及用于提供能够自适应地处理一系列功率输入的充电器的系统，方法和装置。 充电器可以选择性地激活充电器内的不同的控制开关，以便更有效地使用提供给充电器的电流。 当向充电器提供低功率输入时，充电器可以减少用于提供来自充电器的电压输出的有源控制开关的数量。 以这种方式，可以减少切换控制开关所需的电容。 当向充电器提供高功率输入时，可以增加有源控制开关的数量，以便增加可从充电器提供的总电荷量，从而减少电池的充电时间。

Abstract: A power conversion circuit providing a regulated output voltage to a load can include a switching regulator with an input configured to be coupled to an input voltage source and an output configured to be coupled to the load. The power conversion circuit can further include a metered charge transfer converter, such as a charge pump or a switched or pulsed current source, having an input configured to be coupled to an input voltage source and having an output configured to be coupled to the load. A controller coupled to the metered charge transfer converter can be configured to operate the metered charge transfer converter to deliver energy to the load responsive to a dip of the regulated output voltage below a threshold caused by an increase in current drawn by the load. The metered charge transfer converter may be located closer to the load than the switching regulator.

Abstract: The present disclosure describes a system with a power management device, a wakeup circuit, a battery management device, and a connector. During a powered down mode of operation, the battery management device can provide, via the connector, a bias voltage to the wakeup circuit. In response to a wakeup switch being activated, the battery management device can provide a power supply (e.g., from a battery) to the power management device. Benefits of the wakeup circuit include (1) a reduction of battery consumption—and thus improving battery lifetime—when the electronic system is in a powered down mode of operation because the wakeup circuit has lower number of active components compared to other designs and (2) a non-complex wakeup circuit design because one or more existing connector interconnects between the power management device and the battery management device can be re-used during electronic system's powered down mode of operation.

Abstract: A power conversion circuit has multiple phases wherein each of the phases has an inductor coupled to a power switch circuit and is coupled to an output node. A power conversion controller controls the switching of one or more of the phases to yield a regulated voltage on the output node. The controller uses a variable inductor current limit for one or more designated phases, and temporarily increases the variable inductor current limit during a transient condition. Other embodiments are also described and claimed.
