Description

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
