Part Number: UC2843A-Q1

Tool/software:

Did TI make a design change between July 2022 and October 2024 that resulted in the changes to maximum lead temperature and package thermal impedance as cited in the October 2024 datasheet?
Was a PCN issued for the 300mm redesign and did that redesign result in any updates to the October 2024 datasheet?
Is there a date code associated with cut in of the October 2024 datasheet revision?
When TI tests each part for functionality, is it done at any temperature other than room temp?

Hi,

Yes

No, the codes cannot be used for ID of PCN devices or not.

Yes, in short.

1. Understood.

2. Can you provide the PCN # & Link?
3. Effective Date?

4. What are the test temperatures?

Hi,

Can you check your TI contact for PCN? Based on your company name, TI should send the PCN to your company directly. To avoid possible misunderstanding, please talk to your PCN contact about PCN's or send a message to your TI FAE for further support.
