摘要:
A wireless power receiver according to some embodiments includes an integrated circuit which includes: a full-bridge rectifier coupled to receive wireless power from a receiver coil; a wireless receiver controller coupled to control the full-bridge rectifier; a pass device coupled between the full-bridge rectifier and an output; and a configurable controller coupled to the switch, the configurable controller configurable as a LDO controller or a Buck controller. A second controller can be coupled to the configurable controller that interfaces to an external Buck low-side transistor if the configurable controller is the Buck controller and provides GPIO if the configurable controller is the LDO controller. A third controller can be coupled to the full-bridge rectifier, which operates as a full-bridge sync rectifier driver multiplexer to select an external driver for one or more of the rectifier transistors. Other features are also provided.
