I don't know...
I repeat:
You may take some pictures of the PCB (component side/solder side) and later attach them here. Based on PCB photos, there's a chance to discover a suitable replacement.

I need to replace this ic in the picture ,
This is the power supply ATX model : dell h280p-01 power

:) Yes, that’s perfect, but I need also some pictures of the PCB solder side (This will help identify functionality of the IC).

The circuit it’s part of the TinySwitch family.
Here we find TNY279 /TNY280 series (typical oscillator frequency 132Khz) and TNY379/TNY380 series (typical oscillator frequency set to an average of 264 kHz).
Datasheet details:

I think they are using TNY279 /TNY280 series circuits. Need to check also if the optocoupler is defective, see photo details…
