Tool/software:

Hi team,

I saw the Tj and Ta are both -40 to 85degC, it does confuse me.

In general, Tj will higher than Ta, please help to clarify what Tj is correct.

My customer want to know the Tc for 5V PVDD and 2W output.

Thanks and Best regards,

Tiger

It seems the formatting of the Abs Max table was wrongly edited in the last revision; you can refer to the capture below of a previous revision with the correct values:

Thanks Ivan.

One more double check.

The datasheet shows the Tc,top is 0.6 degC/W, is it correct?

Thanks and Best regards,

Hi Tiger,

Are you referring to the second line in table 8.4? That shows 0.7 C/W.
