Those capacitor are for charging gate drivers for different audio signals(various bandwidths) and those work on 12v or 5v supplies depending upon the tpa32xx you use. So a 25v cap is enough.
No need to provide additional supply. You will just fry the board. Bst means bootstrap. You can try on any ab class ic to see what it does which has a bootstrap cap. 😜

I have a BDM8-A TPA3255 and I am powering it with a 48 volt switching power supply. The round rocker on /off with a LED switch I was using in the chassis blew probably because it is not rated for 48 volts. I have the LED in the switch powered off of a voltage step down thingy. What power switch should I use? I have been looking to find a switch but most everything is rated for 12 volts. I did find one that was rated to 30 volts.
My switch worked fine for a year at 27-36 volts with another amp board. I guess 48 volts was just to much.
Thanks Scott

Hi,
Switching DC is problematic due to arcing. So normal switches may not last long.
You can try a solid state switch as it does not care about arcing :

Otherwise, better to put a switch on AC mains line.
