TPA3132D2: 10V power supply, PBTL mode can reach the maximum power

user5707026

Part Number: TPA3132D2

AUDIO PA I want to use tpa3132d2, but there is a parameter spec not marked, this parameter is 10V power supply, PBTL mode can reach the maximum power, corresponding to 16ohm and 3.2ohm speaker respectively.

Thanks.

Hi Engineer,

The main problem is that 85W can be achieved at 19V.

We design the input voltage range to be at least 10V.

Therefore, you need to help confirm the output performance of the 16 ohm and 3.2 ohm PBTL mode load at 10V.

Thank you.

Hello,

Can you provide more detail information to us?

THD? 1% or 10% for max power?
Gain?
Do you have thermal request?

We can test on EVM board.

hello,

if we account inductor DCR as 100mohm, 3.2ohm 1% THD max power around 14W and 10% THD is ~17W. for 16ohm, 1% THD is around 3W and 10% THD is ~3.8W.
