The STWLC33 is an integrated wireless power solution suitable for portable applications. The STWLC33 is able to operate with Qi 1.2 or AirFuel inductive communication protocol. It can operate up to 15 W receivers or 5 W transmitters.
●Thanks to the integrated low impedance synchronous rectifier and the low drop out linear regulator, the STWLC03 achieves high efficiency and 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 CSP package is suitable for very compact applications.
