TPS53355: Recommended Replacement

Yuto Sakai

Part Number: TPS53355
Other Parts Discussed in Thread: TPS53319, , TPS548A20, LMZ31530

Hi,

I have a question about TPS53319 and TPS53355.
Looking at these products page, other devices are introduced as "recommended alternative parts" for these devices.

TPS53319 → TPS548A20
TPS53355 → LMZ31530

Could you tell me the background of these statements?

Best Regards,

Sakai-san,

They are just possible alternatives. Suppose you are looking at TPS53355 and it looks god, but you really would rather have a module. In that case TI suggests you look at LMZ31530. We are not suggesting that you should use it instead, but just showing other possibilities.

Hi John-san,

Thank you for your reply.
I understand the background that LMZ31530 is introduced as a replacement recommended product of TPS53355.
Could you tell me the reason why TPS 548A20 is recommended for TPS53319?

Best Regards,

It is the same reason. The product page just offers possible alternatives. We are not suggesting that you pick TPS548A20 instead of TPS53319 unless you would rather use it.

Hi John-san,

TPS548A20 is not a module, why is there a recommendation reason compared with TPS53319?

Sakai-san,

It is just a similar part with the same input voltage range and similar (14 A vs 15 A ) current rating. The page is only mentioning possible alternatives if you are looking for something different.
