Part Number: TPA3131D2

Hi,

Current limit value of TPA3131D2 is specified 3.4A(typ).

Could you provide 3σ of this value for our reference?

I don't require guarantee.

Hi Kuramochi,

We need more time to check final production data for detailed 3σ value.

BTW, could you help us understand the purpose of this requirement?

Regards,

Matthew

Matthew-san,

Thank you for your reply.

We would like to check if TPA3131D2 can be used on 10W output condition.

Best Regards,

Kuramochi

Hi Kuramochi-san,

As below figure shows, it's not recommended to use TPA3131D2 with 4ohm load due to current limiter (inductor ripple current should be also taken into consideration)

Regards,
Matthew
