Abstract
Described herein is an apparatus having a wireless power receiver comprising a receiver coil used to receive power wirelessly and to communicate wirelessly. The wireless power receiver outputs power to a bus based on the wirelessly received power. The apparatus has an open-loop DC-DC converter and a linear regulator. The apparatus has a controller configured to enable the open-loop DC-DC converter to use the power on the bus to charge a battery. The controller is further configured to control the linear regulator to stabilize a current in the bus at the output of the wireless power receiver to reduce interference to the wireless communication when using the receiver coil to wirelessly communicate from the wireless power receiver to the transmitter of the power while the open-loop DC-DC converter is being used to charge the battery.
