TPA3116D2: Inductors and chip are very hot, untouchably hot

Hi 

Could you share schematic and PCB layout to us?

Thanks!

Here are the Schematics and the PCB layout's. I've temporarily put a 12V supply on it, but i intent on using a 19,5V supply.

Hi Jip

What's the output power on mono mode? The Isat of inductor is related to output power.

And double confirm the 1nF and 3.3R+10nF circuit bom are correct, you can remove them and double check again.

How can I know the output power? 100W max in PBTL right?.

The values are correctly placed. Should I change them? I followed the datasheet and the EVM module.

Hi Jip

Firstly, you can short audio input through 1uF capacitors, and check idle current. It can exclude the possibility that input noise lead current increase.

I have 1uf connected to the output from my PC. When that is outputting sound or not it get's warm. I even put some 30A inductors on, where the ic get's hotter than the dual channel IC. I still have to check the idle current though.
