Dear all:
I used TPA3111D1 to do the temperature rise experiment, electrified and turned on the horn. After 20 minutes, I found that the inductance temperature of TPA3111D1, L2 and L3 was very high, about more than 100℃.Although the chip is not damaged, the temperature of this part of the chip is too high, resulting in high ambient temperature
Attached are the schematic diagram and PCB, please help to provide improvement Suggestions?
Thank you!
