1 0,9/2016 Overview Description The WCT1111 is a wireless power transmitter controller that integrates all required functions for WPC “Qi” compliant wireless power transmitter design.
It is an intelligent device that works with the NXP 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 WCT1111 controls the power transfer by adjusting the operation frequency and duty cycle, or switching topology, or adjusting the phase difference of the power stage according to message packets sent by the mobile device.
To maximize the design fr...
