Hi,

We have two questions, related with package.

*1.

What is different between DDA (R-PDSO-G8) and DDA0008A package?

I think PowerPAD size is different, but please confirm it.

*2.

Which packages does TI use for LMR33610?

Please advise us.

Thanks and best regards,

M.HATTORI.

Hi, Hattori,

The package outline of the two package types are the same, the difference is the size of thermal pad.

This device is built by two different sites using different lead frames.

One site use DDA R-PDSO-G8 and the other use DDA-0008A.

The suggestion is to use DDA -0008 size for thermal pad design to cover both cases.

now I see on DS is DDA0008J,

Hi, Hattori-san,

LMR36510 and LMR33610 is the same package . The suggestion is to use 2.34x2.34mm size for thermal pad to cover both cases. The reason is to prevent solder pollute.
