Hi Allen,

Please find the below chart for Output power vs PVCC in PBTL mode with 4Ohm load. The green curve is for 10% THD+N, while the red one is for 1% THD+N.

Best regards,

You mean the PBTL output power max is only 64W at 4ohm(THD+N 10%) ??

Yes, in this case, the linear max output power is limited by the PVCC voltage.

3ohm 23V Input output power 100W ,4ohm 23v Input output power 62W(THD+N 10%)
Do you think the answer is reasonable?

Allan,
I can't quite understand your concern. It's expected that the max output power is higher with lower load resistance under the same condition. Could yo please help to explain your concern?
Best regards,
