We designed amplifier board ( in single pcb there are 3 amplifier units ) using TPA3244.
It work only for 1-3 minutes Fault LED light up and amplifier stop working. ICs are getting hot.
What is strange is when I touch the top left corner pads of IC package, Fault led lights up again and amplifier start to work.
And stop again in 1-3 minutes.
Please let me know possible issues. I can share the design if it is requested.
Thanks
