The P9036B is a highly-integrated WPC-compliant wireless power transmitter IC for power transmitter WPC design TX-A6 which meets the requirements for compliance with the WPC 1.1 standard. The device operates with a 12Vdc adaptor, and it offers both internal and external half-bridge inverters enabling this single part to serve in either type of application. It controls the transferred power by changing the switching frequency of the half-bridge inverter from 115kHz to 205kHz as specified by the WPC specification for an "A6" transmitter. It contains logic circuits required to demodulate and decode WPC-compliant message packets sent by the mobile device to adjust the transferred power. NOTICE: This device is restricted to high-volume and strategic applications only.
