IDT has introduced two reference kits for wireless power charger applications supplying from
5W to 15W.

The IDT wireless power reference solution is comprised of a transmitter board, the P9242- R-EVK, and a receiver board, the P9221-R-EVK. Both comply with the Wireless Power Consortium’s WPC-1.2.2 standard, marketed to consumers under the Qi® brand. The IDT reference system achieves peak efficiency of 87% when supplying a 15W load.

The reference kit provides a comprehensive design template for immediate prototyping. An associated layout module may be directly copied to a system board, while an optimised and fully-tested bill-of-materials provides a ready-made component selection.

In addition, the extensive digital library of technical support materials provides answers to questions and problems raised by design engineers implementing the system.
