SYSTEMS AND METHODS FOR ENABLING A UNIVERSAL BACK-COVER WIRELESS CHARGING SOLUTION
First Claim
1. A wirelessly chargeable apparatus, comprising:
- an input configured to be connected to an output of a cover of the chargeable apparatus; and
a converter circuit configurable to be coupled to one of a plurality of receive antennas on the cover of the chargeable apparatus via the input, 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, the converter circuit configured to;
selectively receive an input voltage from the one of the plurality of receive antennas;
operate in a first mode to produce a first output voltage, at an output of the converter circuit, 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 converter circuit, that is scaled relative to the input voltage based on a second relationship between the input voltage and the voltage level threshold.
