Abstract: A charger circuit includes an interface connector coupled to a power adapter that provides an input signal having an input voltage, and a buck-boost converter circuit that may be coupled to a battery having a charging voltage. At a given time, the buck-boost converter circuit operates in a mode in a group of modes based on a control signal, where the group of modes may include at least a buck mode and a boost mode. In particular, the charger circuit includes control logic that generates the control signal based on the charging voltage and a charging capability of the power adapter. Thus, if the charging voltage suitably exceeds the input voltage, the buck-boost converter circuit may operate in the boost mode. However, if the charging voltage is approximately less than or equal to the input voltage, the buck-boost converter circuit may operate in the buck mode.

Abstract: A wireless power transmitting device may transmit power wirelessly to a wireless power receiving device. The wireless power receiving device may be a portable electronic device with an array of wireless power receiving coils that receive wireless power from wireless power transmitting coils in the wireless power transmitting device. Each receiving coil in the array of wireless power receiving coils may be coupled to a respective rectifier. Control circuitry of the wireless power receiving device may be configured to determine which rectifiers to enable for synchronous rectification. The control circuitry may be configured to enable at least one rectifier based on the alternating-current voltages produced by each coil in the array of receiving coils. The control circuitry may also be configured to enable at least one rectifier based on the output current from each rectifier.
