Integrated Device Technology 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 3W or less, such as smartwatches, headphones, health and fitness trackers and portable medical devices.

Suited for applications ranging from 0.5-3W, 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 groundbreaking 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.

Dave Shepard, Vice President, Consumer Products Division, IDT, commented: “We recently announced that we had delivered over 70m wireless power devices to date, indicating that wireless power has truly entered mass adoption phase. We now anticipate large-scale wireless power adoption in segments such as smartwatches, fitness and health monitors. With the low-power kit, we want to follow the success of our easy-to-use 5W kit, which opened the market to customers who don’t have the expertise, budget or time to develop a custom solution.”

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, 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.

“This new kit offers Digi-Key customers the opportunity to fast-track wireless charging integration into their compact electronic devices. And just like the 5W kit, next-day delivery helps engineers go from concept to prototype in fewer than 24 hours,” added David Stein, Vice President, Global Semiconductor, Digi-Key Electronics.

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