Hello Bing,

Running GVDD below 10.8V will trip the under voltage protection (UVP) and the amplifier will turn off. 12V is the recommended nominal voltage level for the gate drive.

Has your customer looked at the TPA3255 to replace the TAS5630?
It has significantly better performance and is cost competitive.

Best Regards,
Matt
