TPS2553: Thermal information from SLVS841C to SLVS841F

Hi Kay,

So sorry for the late reply.
I missed your post.
I searched the database and can't find related revised datasheet.
Will ask my co-workers about this issue and reply to you.
Sorry.

Hi Kay,

Can you kindly offer me the dissipation rating table of revision C?
I can't find the C version.
Have sent one e-mail to the related team to ask for that version.
Thanks.

Hi Ziv:

Here is it.

Hi Kay,

I think the dissipation rating table belongs to the JEDEC standard for High-k and Low-k.
The parameters are general standard. All related IC need to sdandby.
So we can delete that table without revision history.

If any concern, contact me any time.

Thanks.

Hi Ziv,

Why the data shows the difference value? Did it change something?

How to distinguish it? By date code? Thanks!

Hi Jerry,

The table of the Old datasheet(2012) is not our part's thermal information.

It means at different board layer and different package, resulting in different thermal parameters.

I think that's just a reference value from standard committee.

For the new datasheet, that's the thermal information of our part.

If you look up the C version old datasheet, it also includes the same thermal information.

If you have other concern, contact me any time.

Thanks.

Hi Ziv,
Understand, thanks for the explain.
