Multi Mode Qi/Airfuel Inductive Wireless Power Receiver with Transmitter Function

The STWLC33 is an integrated wireless power receiver solution suitable for portable applications up to 15 W. The STWLC33 is able to operate with Qi 1.2 or AirFuel inductive communication protocol. It can be switched to transmitter mode to provide power to another receiver. Thanks to the integrated low impedance synchronous rectifier and low drop-out linear regulator, the STWLC33 achieves high efficiency, low power dissipation. I2C interface allows many parameters to be customized in the device and this configuration can be stored in the embedded NVM.

The Flip Chip (3.97x2.67 mm) is suitable for very compact applications.
