The CPS4019 is a highly efficient, Qi-compliant, single-chip Wireless Power Receiver IC. It supports up to 5W applications in the Receiver (Rx) Mode. The device receives AC power from a Wireless Power Transmitter (Tx) and converts it into a rectified output voltage. As a Rx, it integrates a synchronous rectifier and a low drop-out regulator to provide power to system load or battery. Modulation and control circuits are used for bi-directional in-band communication to the Tx.
