概要
The EVALSTWBC-EP is a wireless battery charger TX evaluation kit including EVALSTWBC-EP demo-board and EVALWBCDNGV1 USB-UART dongle, designed for charging devices such as smartphones or tablets where high power levels are required.
The evaluation board supports wireless battery charging of Qi-compliant devices up to 15W. It also supports proprietary fast charging modes up to 10W.
The EVALSTWBC-EP transmitter is based on the STWBC-EP and features a cost-effective half bridge topology offering external interface via UART. The EVALSTWBC-EP solution provides a complete kit, which includes demo board, its firmware, a graphical interface for debug, the schematics, layout files and bill of materials.
Tools for EVALSTWBC-EP are available on www.st.com and allow users to access runtime information such as power delivered, regulation error and protocol status. Parameters can also be adjusted with these tools
