Im using BQ51013ARHL as a receiver for wireless charging, BQ24079T receives power 5V from it to charge LiIon battery at 4.2V and finally it connects to TPS77833 LDO to provide 3.3V output to the system.
hovewer during charging especially RX coil becomes extremely hot. When the board is not packed into casing its still ok, but once I put it into casing it becomes extremely hot very fast. Any idea what could be the case?
Thanks,
Sergey
