Wireless Power Transfer

Analog Devices’ wireless power transfer portfolio helps eliminate many of the issues that designers face when powering their applications. Our wireless charging design allows for completely sealed enclosures for applications that require sterilization, or for applications that are too small to use a conventional connector. Eliminating wires also allows for rechargeable batteries to be placed in moving or rotating equipment. Wireless charging can provide transformerless galvanic isolation for high reliability isolated applications. Our products were developed with PowerbyProxi, a field-proven technology company focused on providing real-world wireless power solutions.
