Reference Kit Eases Wireless Design

Integrated Device Technology, Inc. has introduced a wireless power reference kit that helps make integrating wireless charging into compact electronics easy and affordable. The IDT® Qi-based transmitter and receiver reference kit targets designs requiring 3 W or less, such as smartwatches, headphones, health and fitness trackers, and portable medical devices.

Suited for applications ranging from 0.5–3 W, the reference kit comprises both a transmitter (P9235A-R) and receiver (P9027LP-R), with three different coil size options supporting various applications, form factors and power levels. The comprehensive kit enables immediate prototyping, meaning engineers can incorporate wireless charging capabilities into their ultra-compact designs in a matter of hours.

The kit’s associated layout module allows for direct instantiation on to a system board, while an optimized and fully tested bill of materials (BOM) takes the guesswork out of component selection. In addition, an extensive digital library of collateral eliminates traditional design and support barriers regardless of application volume.

Support materials include user manuals, layout guides, layout instantiation modules, schematics, BOM, Gerber files and more. Delivering peak 80% system efficiency at 3 W, the kit offers seamless integration with the drop-in reference layout provided, and an optimized thermal design.

The wireless power kit containing the transmitter, receiver and additional coils is priced at $70.
