IDTP9022 Application Block Diagram


Enhanced WPC 1.1 Wireless Power Receiver

The P9022 is an enhanced single-chip wireless power receiver that complies with Wireless Power Consortium’s WPC 1.1 requirements for certification. Integrating a high-efficiency synchronous rectifier, high-efficiency buck converter, and control circuits, the P9022 provides output power up to 5W in accordance with the Qi specification. Users operating the P9022 together with an IDT wireless power transmitter can obtain power transfer up to 5W by utilizing a proprietary back-channel communication protocol, which expands upon the WPC-specified protocol to achieve higher power transfer using the advanced control loop.
