The P9261-3C-CRB is a turnkey 15 Watt, Qi-compliant wireless power transmitter triple coil reference kit for fast prototyping and design integration. This will enable customers to have faster time to market with a WPC Qi qualified MP-A13 three coils solution. The kit consists of an easy-to-use 3-coil WPC Tx type reference board and 15W EPP receiver board, P9221-R-EVK and comprehensive design collateral that significantly eases design-in effort and minimizes time-to-market.

An associated layout module enables direct instantiation on to a system board, while an optimized and fully-tested Bill-of-Materials (BOM) takes the guess-work out of component selection. The P9261 based solution is well-suited for automotive in-vehicle wireless power charging. It meets AEC-Q100, grade 2 standard and CISPR-25 EMI/EMC performance.
