Wireless power reference kit targets 3W or less designs

The WP3W-RK wireless power reference kit from Integrated Device Technology (IDT) is available at Mouser Electronics. The new Qi-based transmitter and receiver reference kit helps make integrating wireless charging into compact electronics easy and affordable, targeting designs requiring 3 W or less, such as smartwatches, headphones, health and fitness trackers and portable medical devices.

Building on the success of IDT’s 5W reference kits, this kit enables immediate prototyping, letting engineers incorporate wireless charging capabilities into their ultra-compact designs in a matter of hours.

It is a high-efficiency, turnkey reference design that can help ease design-in efforts and enable fast prototyping.

Suited for applications ranging from 0.5 – 3W, the reference kit is comprised of both a P9235A-R transmitter and a P902LP-R receiver, with three different coil size options supporting various applications, form factors and power levels.

Delivering peak 80 percent system efficiency at 3W, the kit offers seamless integration with the drop-in reference layout provided and an optimised thermal design.

The kit’s associated layout module allows for direct instantiation on to a system board, while an optimised and fully tested bill-of-materials (BOM) takes the guesswork out of component selection.

In addition, an extensive digital library of layout guides, schematics, Gerber files, and more eliminates traditional design and support barriers regardless of application volume.
