The STWLC89 is a highly integrated wireless power receiver suitable for applications delivering an output power up to 30 W.

The STWLC89 shows excellent efficiency performance thanks to the integrated low-loss synchronous rectifier, regulation dynamically managed by the digital core to minimize the overall power dissipation over a wide range of output load conditions.

Through the I²C, interface the user can access and modify the configuration parameters, tailoring the operation of the device to the needs of customized applications.

The final configuration parameters are stored in the embedded nonvolatile memory (FTP) and automatically retrieved at power-up, allowing the STWLC89 to operate as a standalone device.

Reverse Charging Tx Function for Smartphone Applications only.

The device is housed in a chip scale package to fit real-estate applications with reduced BOM count.
