Qi Compliant Wirless Power Transmitter MODULE

The WCM-TP6735 is a Wireless Power digital controller for Qi Compliant Wireless Power Transmitter design A5 and A11. The device operates with a 5V (±5%) adaptor, and utilizes an external full-bridge inverter to provide a solution for A5/A11 transmitter applications. It controls the transferred power by modulating the switching frequency of the full-bridge inverter from 110kHz to 205kHz at a fixed 50% duty cycle specified by the WPC specification for an A5/A11 transmitter.
