NOTICE - The following device(s) are recommended alternatives:

The IDT P9035A is a highly-integrated WPC-compliant wireless power transmitter IC for power transmitter design A5 and A11, which meets the requirements for compliance with the WPC 1.1 standard. The device operates with a 5V (±5%) adaptor, and utilizes an external full-bridge inverter to provide a highly-efficient 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. It contains logic circuits required to demodulate and decode WPC-compliant message packets sent by the mobile device to adjust the transferred power.
