The 22W watt MP-A11 single-coil fixed frequency wireless charging transmitter reference design uses the WCT10xx transmitter controller IC that integrates all required functions for the Wireless Power Consortium (WPC) Qi-compliant wireless power transmitter design. This solution uses NXP touch sensing technology or analog PING to detect a mobile device for charging while using the lowest possible standby power. To maximize design freedom and product differentiation, the WCT101x supports extended power profile (EPP) for industrial and consumer power transmitter designs (WPC MP-Ax types, MP-Bx types or customization) using fixed frequency control methods such as rail voltage control, phase difference control or duty cycle control. This software-based solution supports wireless charging for both EPP and baseline power profile receivers. In addition, the easy-to-use FreeMASTER GUI tool offers configuration, calibration and debugging functions to provide user-friendly design experience and significantly reduce time-to-market.
