Abstract: Devices and methods for controlling a power supply of a wireless power transmitter based on the request of a wireless power receiver are disclosed. One embodiment provides a wireless power receiver. The wireless power receiver includes a power receiver circuit configured to receive power from a wireless power transmitter at a level sufficient to power or charge a load. The wireless power receiver also includes a processor circuit configured to adjust a level of the received power being provided to the load based on a change in a level of received power to be requested to the wireless power transmitter. The processor circuit is further configured send to the wireless power transmitter the request to change the level of the received power to a first different level.

Abstract: A dual port charging architecture is generally disclosed. For example, the dual charging architecture may include a first board portion having a first battery port configured to be coupled to a first set of battery terminals of a battery, a second board portion having a second battery port configured to be coupled to a second set of battery terminals of the battery, a connection portion electrically coupled between the first board portion and the second board portion, a first power path coupling a power input port of the second board portion to the first battery port via the connection portion, and a second power path coupling the power input port to the second battery port.

Abstract: Some examples of the disclosure include a low profile inductor for use on a printed circuit board to minimize the area occupied and enable easier breakout routing and opening up additional area for other components. In one example, an inductor may include a cavity with diode, such as a low profile diode, that does not increase the area occupied by the inductor.
