Hi,

My post is about the IRAUDAMP23 evaluation board. It can provide 2x500W power ; my question is : is there a limitation to the 500W ? If yes, how is made this limitation and how to change this limit ?

Thank you

Hi,

As you can see from the Electrical data of the IRAUDAMP23, you can achieve 600W per channel but the THD+N drastically increases from 1% at 500W output to about 10% at 600W.

Therefore its not recommended to use it above 500W. 

I hope this document will also help you in designing - https://www.infineon.com/dgdl/Infineon-ClassD_Audio_IRS2452AM_functional_description-ApplicationNote...
