The device operates with a 12V (5%) adaptor, and supplies an integrated half-bridge inverter for DC/AC conversion. It controls the transferred power by modulating the switching frequency of the half-bridge inverter from 115kHz to 205kHz at a fixed 50% duty cycle as specified by the WPC specification for an "A6" 3-coil transmitter. It contains logic circuits required to demodulate and decode WPC-compliant message packets sent by the mobile device to adjust the transferred power. The IDTP9036 manages all 3 coils in the WPC TX-A6 configuration, performing detection and charging control without user supervision. It also features a proprietary back-channel communication mode compatible with other IDT Wireless Power prodEVALUATION BOARD ucts which provides additional secure authentication capabilities, in addition to implementing the WPC-specified device identification communication sequence and closed-loop control protocol, which constantly adjusts transmitted power. VALUE ADDED BEYOND WPC "QI" * Delivers industry-leading power to receiver (5W to WPC-compliant receivers, more when using IDTP9020 Receiver) * Optional, proprietary Back-Channel communication provides additional levels of encryption and security * Manages power transfer fault conditions automatically and controls status indicator LEDs DISCLAIMER Integrated Device Technology, Inc.
