WLC1150-68LQXQ

WLC1150-68LQXQ is a wireless charging IC (WLC). It is a highly integrated wireless power transmitter, ideal for 50W charging applications. The IC works in Infineon high power proprietary protocol mode to deliver 50W power. It offers a cost-effective solution for various applications up to 50W output power, by addressing critical system needs of high-power application, like thermal, EMI, foreign object detection (FOD), high efficiency and inverter control, and so on. It offers compatibility with various types of input configurations to address wide range of high-power applications. It supports systems with input power supplied by either USB PD/PPS or fixed input from DC power supply. Potential applications include wireless charging pads with power proprietary protocol (50W), industrial wireless charging applications, vacuum cleaner, robotics and drones, furniture and home goods, docking stations, smart phone charger with Qi EPP (up to 15W).
