Accelerating adoption of wireless power in compact, low-power applications

Integrated Device Technology (IDT) has introduced a wireless power reference kit claimed to 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 to 3W, the reference kit is comprised of both a transmitter (P9235A-R) and receiver (P9027LP-R), with three coil size options supporting various applications, form factors and power levels.

Building on IDT’s 5W reference kits introduced last year, the latest kit enables immediate prototyping, meaning engineers can incorporate wireless charging capabilities into their ultra-compact designs in a matter of hours.

A digital library of collateral is said to eliminate traditional design and support barriers regardless of application volume. Support materials include user manuals, layout guides, layout instantiation modules, schematics, bill-of-materials, 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.
