TPA3116D2: TPA3116D2 output overcurrent

Part Number: TPA3116D2

It found that the output overcurrent protection when TPA3116D2 in master/slave synchronous operation, caused the output power decline in100HZ.

If the IC works separately are normal. It also works stably above 1KHZ. If the master SYNC pin connect a 10K resistors to GND, the output inductance heats very badly.

  • Hi 

       The low frequency is indeed easily trigger OC. May I know what is your input/output voltage level, also what is the speaker resistance value you are going to use? Also what is the part number of your inductor, is the rated current for this inductor sufficient?
