It is an intelligent device that works with the Freescale touch sensing technology or uses periodically analog PING to detect a mobile device for charging while gaining super low standby power. Once the mobile device is detected, the WCT1012 controls the power transfer by adjusting operation frequency and duty cycle, or switching topology, or adjusting the phase shift according to message packets sent by mobile device. In order to maximize the design freedom and product differentiation, the WCT1012 supports medium power consumer power transmitter design (WPC MP-Ax or customization) by using operation frequency and duty cycle control, phase shift control, and topology switch by software based solutions, which can...
