REF_WLC_TX15W_C1
The WLC MP-A11 15W wireless power transmitter reference board (REF_WLC_TX15W_C1) demonstrates the functionality
of the Infineon WLC1115 wireless charging transmitter controller. It implements the Qi v1.3.2 specification and supports 15W
wireless charging using Qi Extended Power Profile (EPP). It also supports Qi's Basic Power Profile (BPP) to support 5W wireless
charging with receivers which do not support EPP. This reference board is powered using a USB-C power adapter that is
compliant with USB PD 2.0 and higher specifications.
