I have an uPC1188H power chip circuit that has some parts missing in the feedback loop. Would like it if someone has a support circuit for this chip. It works but is not stable and has some offset also.

This matter could be discussed if you show the actual current schematic.

Here I could find only a test circuit in the datasheet. https://pl-1.org/getproductfile.axd?id=3142&filename=uPC1188H.pdf
