Hi Shraga

I'm afraid 6ohm is too large resistance for 300W. If you use a sinewave to calculate, it needs at least 60V voltage, out of device TPA3255 working range.

So what is the best resistance and voltage to get close to 600W ?

we also asked for the bet EVL board setting to get the max power at MONO mono mode ?

Hello Shraga,

Section 6.8 in the TPA3255-Q1 Datasheet says the load and supply voltage that is used to drive 600W, Section 9.2.4 has the circuit for mono PBTL

Refer to section 4.2 in the TPA3255EVM User's Guide if you using an EVM on how to configure mono PBTL.

best regards,
Luis
