IDT’s wireless power reference kit is targeted for applications ranging from 0.5 to 3W. The reference kit is comprised of both the transmitter (P9235A-R-EVK) and the receiver (P9027LP-R-EVK) with three different coil size options supporting applications with different form factors.

The comprehensive, turnkey reference design enables immediate prototyping. An associated layout module allows for direct instantiation on to a system board, while an optimized and fully-tested BOM takes the guess-work out of component selection. In addition, the extensive digital library of collateral eliminates traditional design and support barriers regardless of application volume.
