Hello robert11, welcome to the DigiKey TechForum,
The only LED driver in our system with an output of 1.28A is the PLC-040S128D, unfortunately this is obsolete. There is a similar alternative to this on the product page, part number 1121-1308-ND, but this has a slightly higher output current of 1.4A. I did search our system for other alternatives and the closest stocking options have an output of 1.19A or 1.4A with slightly different voltage ranges, I linked these options HERE. These clearly don’t have the current output you are looking for so they are obviously not drop in replacements, please check the datasheet to see if they will work for your application.
