Now Bring Wireless Charging To Ultra-Compact Electronics


Integrating wireless charging into compact electronics is now made easy and affordable with a new wireless power reference kit from IDT. The 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.

The comprehensive kit enables immediate prototyping, meaning engineers can incorporate wireless charging capabilities into their ultra-compact designs in a matter of hours.

Delivering peak 80 percent system efficiency at 3 W, the kit is suited for applications ranging from 0.5 – 3 W. It 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, says the company.

According to Dave Shepard, vice president of IDT’s Consumer Products Division: “We recently announced that we had delivered over 70 million 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 5 W kit, which opened the market to customers who don’t have the expertise, budget or time to develop a custom solution.”


Associated with the kit are a layout module to allow for direct instantiation on to a system board, and a fully tested BOM. 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

Create Field-to-cloud IoT Applications In Minutes With New Kit

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

The new wireless power kit containing the transmitter, receiver and additional coils is available now at a suggested retail price $70. Free samples are available for approved customers.
