hi
I have a question about TAS2781 input power.I used an extral 20V/1.75A adapter power for TAS2781EVM,setup under this configurationconfiguration.
I tested PA input power by oscilloscope,I measured PA input Voltage and PA input current,than add a oscilloscope math to count V ride C ,measured average and peak power. The average power conform to theoretical,but peak power higher than theoretical more,even exceed the upper limit of adapter.So i try to add some buck capacitor for decreasing peak power.If you have some experience in theoretical analysis, calculation, and simulation model construction or other methods for similar question.
thanks!
