Reference kit brings wireless power to compact, portable apps

Integrated Device Technology Inc. (IDT) has announced a wireless power reference kit that assists designers in making integrating wireless charging into compact electronics simpler and more cost-effective. The IDT Qi-based transmitter and receiver reference kit targets designs ranging from 0.5W to 3W, such as smartwatches, headphones, health and fitness trackers and portable medical devices.

The reference kit is comprised of both a transmitter (P9235A-R) and receiver (P9027LP-R), with three different coil size options supporting various applications, form factors and power levels.

Building on the success of IDT's innovative 5W reference kits introduced last year, 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 optimised and fully tested 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, bill-of-materials (BOM), Gerber files and more. Delivering peak 80% system efficiency at 3W, the kit offers seamless integration with the drop-in reference layout provided, and an optimised thermal design, indicated the company.

The wireless power kit containing the transmitter, receiver and additional coils is available at a suggested retail price $70 and can be ordered directly from participating distribution partners. Free samples are available for approved customers.
