UCC29002: Difference between UCC29002DR and UCC29002DR/1

Part Number: UCC29002
Other Parts Discussed in Thread: UCC39002,

Hi, TI expert.

Please tell me the difference between "UCC29002DR" and "UCC29002DR/1".

On the datasheet, UCC29002DR and UCC29002DR/1 are both the same as SOIC pakage, only the device marking is different, and there is no explanation for the other differences.

I tried searching for the difference in the question of E2E, but the answer is different.

The E2E answer below explained that it is a functional difference between Start-up and Adjust Logic in section 7.3.8, but if you look at section 7.3.8, UCC39002 has a function and UCC29002 and UCC29001 do not have a function. This doesn't seem to be it.

Also, while answering that the E2E answer below is a difference in packaging, UCC29002-1 answered that it was VSSOP(8) and UCC29002 answered that it was a difference between SOIC(8).
However, if you look at the packing information of the datasheet above, UCC29002DR and UCC29002DR/1 are both SOIC(8).
So, the E2E answer below doesn't seem to be the right answer either.

Can you tell me the exact difference between UCC29002DR and UCC29002DR/1?

It's the exact same device, but only the device marking is different?

If so, is there any reason to separate P/N?

Please confirm
