Description
The P9036B is a highly integrated WPC-compliant wireless power transmitter IC for power transmitter WPC design TX-A6. This device operates with a 12Vdc adaptor, and drives an external load directly via an internal half-bridge. It controls the transferred power by changing the switching frequency of the half-bridge inverter from 110 kHz to 205 kHz 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.
