Kit guides wireless power design-in for low-power applications

May 19, 2016 // By Graham Prophet
This reference kit claims to breaks through the barriers of designing wireless charging into smartwatches, fitness monitors and other wearables; IDT’s wireless power reference kit comprises Qi-based transmitter and receiver for designs requiring 3W or less.

Suited for applications ranging from 0.5 – 3W, transmitter (P9235A-R) and receiver (P9027LP-R), support three different coil size options for various applications, form factors and power levels. IDT already has a similar kit at 5W power level; “With the low-power kit, we want to follow the success of our 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 optimized and fully tested BOM takes the guesswork out of component selection. In addition, a 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), and Gerber files. Delivering peak 80% system efficiency at 3W, the kit offers seamless integration with the drop-in reference layout provided, and an optimized thermal design.

 

“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 5W kit, next-day delivery helps engineers go from concept to prototype in fewer than 24 hours.”

 

The wireless power kit containing the transmitter, receiver and additional coils is available now for $70. Free samples are available for approved customers. Video clips are at;
