WIRELESS PARALLEL CHARGING

A battery charging circuit includes a buck converter, a charge pump power converter, a sensor external to or internal to the battery charging circuit, and a control unit. The charge pump power converter includes an output coupled to an output of the buck converter for charging a battery. The sensor is configured to sense a total input current. The control unit receives the total input current that is sensed and compensates for a variation in an input current to the charge pump power converter based on whether the total input current meets a specified current variance.
