A client has an existing design for an AC-DC5V adapter that uses a Power Integrations SC1144D1; the datasheet is from 2014.  Is this part obsolete?  If so, is there a recommended replacement?

Thank you.

Have there been any revisions to the datasheet?


The part appears to be part of the Link Switch family.  Do the Link Switch application notes apply?  The datasheet I have doesn't have any layout guidelines.

Hi ellement,

No, this is very similar to LNK6406D. For this particular product of your concern, SC, I would suggest you contact our local sales in your area.

Thank you and regards,
