STEVAL-ISB044V1
Qi MP-A10 15 W wireless charger TX evaluation kit based on STWBC-EP

The STEVAL-ISB044V1 evaluation kit has been designed for devices, such as smartphones or tablets, requiring high power levels.

It supports wireless battery charging up to 15 W.

The embedded STWBC-EP digital controller transmitter is based on a cost-effective half-bridge topology providing external interfaces via UART and IC.

The kit also includes STWBC-EP firmware, a graphical interface for debug, schematics, layout files and bill of materials.

There are specific tools for the STEVAL-ISB044V1 available on www.st.com which give runtime information, such as the power delivered, the regulation error or the protocol status as well as parameter tuning.
