SP3100 and NU1007 NuVolta 符合Qi标准的无线充电应用设计方案

SP3100 and NU1007 Evaluation Module

SP3100 and NU1007 evaluation module (EVM) is a 5V-10V input and 10W output, high efficiency WPC wireless power transmitter. The design presents two-chip solution in small package with minimum component count. It is fully compliant with WPC V1.2.3, and yet can be easily customized for any customer-requested solutions. Therefore, the EVM design can communicate with any WPC compliant receivers and guarantee 5W output. The EVM can also support 10W output suitable for fast charger with corresponding coil and receivers.
