TAS6684-Q1: peak power per channel in PBTL application

Christian Kleiner
Prodigy 20 points
Part Number: TAS6684-Q1

Tool/software:

Hi TI team,

according to the TAS6684-Q1 datasheet, running the amp outputs in PBTL increases the output power per channel from 215W to 238W (at PVDD = 45 V, 4 Ω, THD = 1%).

I can‘t find a statement regarding peak power in PBTL. What peak power per channel can i expect at 4Ω, PVDD = 45V in PBTL?

Best Regards,

Christian

    Christian,

    PBTL only allows you more current into a lower impedance load, but does not allow for any more voltage.  At this point you are voltage limited, and the power will not increase in PBTL from BTL when the impedance is 4 ohms.
