I'm using only 1 x TPA3116, I wonder what I do with pin sync (pin 16), leave open, put a resistor to ground ??

Hi, Fernado,

In your case, just leave the SYNC pin open/float when are using it in master mode.

reg,

Paul.

Hi, Paul,

Then I define it as MASTER and leave the pin open. ok.
Regarding Plimit in data-sheet (page 17), there is a table of examples.
In the first PVDD = 24V, Plimit in GVDD, resistors (short and open) case
In this situation it is set to master too?
which the current source required for maximum power?

Yes define as master on the Plimit settings as well.

If your Vdd is 24V and you need 50W peak, your peak current is ~2A.. just add about 3x1000uF electrolytic caps with low ESR. These will take most of the peak current during a bass-boom.

paul,

Many thanks for the information, as they arrive plates sample'll do the tests.
