Abstract: Systems for charging a battery are provided, the systems comprising: a regulator having an output coupled to the battery and having an input; a wireless charging receiver having an output coupled to the input of the regulator and having an input that receives a power signal from a wireless charging transmitter; a controller having a first input coupled to the input of the regulator, having a second input coupled to the output of the regulator, and having a first output coupled to the wireless charging transmitter, wherein the controller is configured to send, using the first output of the controller, a control signal to the wireless charging transmitter that causes the wireless charging transmitter to change the power signal provided to the wireless charging receiver.

Abstract: Voltage regulator systems include, in part, a regulator comprising an input terminal and an output terminal, wherein the regulator is configured to receive an input voltage from an adapter at the input terminal and provide an output voltage at the output terminal, wherein the regulator comprises at least one switched capacitor regulator operating in a first conversion mode corresponding to a first conversion factor. The voltage regulator systems also include a controller configured to control an operation of the regulator, wherein the controller is configured to determine when a conversion ratio of the regulator is greater than the first conversion factor, and, in response, to send a request to the adapter to decrease the input voltage.
