STWLC03数据手册集成电路（IC）的电源管理-专用规格书PDF

描述 Description

The STWLC03 is a high-end WPC and PMA compliant wireless power receiver IC. It includes a wireless power receiver, a programmable buck converter with simplified basic Li-Polymer/Li-Ion battery charger function and the embedded microcontroller, which allows a very wide range of customization and different standard supports. 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.
