Note : Your request will be directed to STMicroelectronics.

The STWLC03 from STMicroelectronics is a Dual mode Qi/PMA compliant wireless power receiver IC that provides up to 12 W of output power. It integrates a wireless power receiver, a programmable buck converter with simplified basic Li-Polymer/Li-Ion battery charger function and an embedded microcontroller which allows for a wide range of customization for different standards supported. The integrated NVM memory stores the customized parameters via JTAG or I2C interface of the device. Thanks to the integrated synchronous rectifier, it achieves high efficiency operations. The buck converter contains the configurable soft-start, input current and input voltage regulation loops to optimize the function in a wireless charging enviroment. If the wireless power is not available, the device can be supplied from an external supply and can connect this supply (5 V adapter/USB) to VOUT through an external switch.

The embedded microcontroller communicates with the host platform through the I2C. The device contains blocks for the frequency detection and the driver for the external switch for the resonant frequency change. The package is a CSP suitable for very compact applications and it has a quad SPI interface with the external Flash memory for firmware development purposes.

It is available in a flip chip 77 bumps package that measures 3.12 x 4.73 mm and is ideal for cellular phones, power banks and navigation systems.
