Systems and methods for enabling a universal back-cover wireless charging solution

A method for wirelessly charging a chargeable device, comprising:

• selectively receiving an input voltage at an input of the chargeable device, from one of a plurality of receive antennas disposed on a cover of the chargeable device, the one of the plurality of receive antennas configured to wirelessly receive power according to a wireless charging protocol different from at least one other of the plurality of receive antennas;
• operating in a first mode to produce a first output voltage that is substantially equal to the input voltage based on a first relationship between the input voltage and a voltage level threshold;
• and
• operating in a second mode to produce a second output voltage that is scaled relative to the input voltage based on a second relationship between the input voltage and the voltage level threshold.

A wirelessly chargeable apparatus, comprising:

• input means connected to an output of a cover of the chargeable apparatus;
• and
• converting means coupled to one of a plurality of receiving means on the cover of the chargeable apparatus via the input means, the one of the plurality of receiving means configured to wirelessly receive power according to a wireless charging protocol different from at least one other of the plurality of receiving means, the converting means configured to:
• selectively receive an input voltage from the one of the plurality of receiving means;
• operate in a first mode to produce a first output voltage, at an output of the converting means, that is substantially equal to the input voltage based on a first relationship between the input voltage and a voltage level threshold;
• and
• operate in a second mode to produce a second output voltage, at the output of the converting means, that is scaled relative to the input voltage based on a second relationship between the input voltage and the voltage level threshold.
