Abstract: A control circuit and method for a synchronous rectifier having a plurality of switches and receiving an AC input signal. The control method includes switching between controlling a first switch of the plurality of switches in response to a control signal for a second switch of the plurality of switches, controlling the first switch in response to a comparison between the AC input signal and a second signal.

Abstract: Methods and apparatus for dynamically selecting one of two power paths in a wireless power receiver. A first power path of the two power paths provides a regulated voltage to output circuitry electrically connected to the wireless power receiver. A second power path of the two power paths provides an unregulated voltage to the output circuitry.
