TPS51200A-Q1: A vs. non-A version

Kannan Sockalingam

Part Number: TPS51200A-Q1
Other Parts Discussed in Thread: TPS51200-EP, TPS51200, TPS51200-Q1

Hi team, what is the difference between TPS51200A-Q1 vs. TPS51200-EP? I believe the -EP is the same as the non-A version of the TPS51200A.

Thanks.

Hi Kannan,

TPS51200A-Q1 is the automotive grade device, while TPS51200-EP is the military grade device with extended temperature range. Hopefully this answers your question.

Weidong,

Thanks.

Why is there an A at the end of the Q1 version? Is this electrically different?

The catalog version (which the -EP is made from) is TPS51200, https://www.ti.com/product/TPS51200

Hi Kannan,

TPS51200-Q1 and TPS51200A-Q1 are two different part numbers. They are electrically the same, but the TPS51200A-Q1 has added polyimide layer to improve reliability.

And you are right that TPS51200-EP is derived from TPS51200.

Weidong
