The WP3W-RK wireless power reference kit from Integrated Device Technology Inc 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 IDT’s 5 W reference kits, the comprehensive WP3W-RK kit enables immediate prototyping, letting engineers incorporate wireless charging capabilities into their ultra-compact designs in a matter of hours.
The WP3W-RK wireless power reference kit is a high-efficiency, turnkey reference design. Suited for applications ranging from 0.5-3 W, the reference kit is comprised of both a P9235A-R transmitter and a P9027LP-R receiver, with three different coil size options supporting various applications, form factors and power levels. Delivering peak 80% system efficiency at 3 W, the kit offers seamless integration with the drop-in reference layout provided and an optimized thermal design.
The kit’s associated layout module allows for direct instantiation on to a system board, while an optimized 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.
