Integrated Device Technology – Reference design kit demonstrates efficient 15W wireless power application


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.
