UCC3805: Datasheet information clarification

Cedrick

Part Number: UCC3805

Hi,

Good day.

Our customer is using the UCC3805 in their project and they noticed some change in the line regulation parameter. Kindly see the description below.

""The Datasheet Rev changed from SLUS270D to SLUS270G but you have not mentioned the change in Line Regulation Parameter that is changed from 2.1 to 2.5.

It is a degraded specification. Please let me know the reason as you have mentioned in PCN's that it is the same device and no changes have been done to the device.""

Looking forward to your inputs. Thank you.

Regards,

Cedrick

Cedrick,

I have the Rev G datasheet from TI.com, can you please attach the Rev D data sheet? Also, can you highlight where you see "Line Regulation Parameter" because this sounds more like a power supply parameter and not an IC parameter? TI does not downgrade/widen IC test parameters without notification through PCN. What PCN number are you viewing? Please show me what you are seeing so I can help?

Regards,

Steve M

Hi Steven,

Thank you for your reply. Here's the Rev Dslus270d.pdf

Kindly see below the snippets..

Furthermore, I've checked the SLUS270F, it seems that the "line regulation" for the UCC380x is not copied on SLUS270G. Can you please help confirm?

Thank you,

Cedrick

Cedrick,

Correct, UCC3 Line Reg is not listed in SLUS270G.
