i need schematic for " dell h280p-01 power supply schematic " , i need its power IC..

Hello
can anyone help me to find the schematic " dell h280p-01 power supply schematic " ?,

Its power IC is burned ,and i need to replace it , but at first i need to see what type is it
so i need its schematic.

THANK YOU

Help !
in this power supply is burned a similar IC (circuit) "

"
can you help to find what exactly is this IC in " dell h280p-01 power supply " .
THANK YOU

is this the same IC at "dell h280p-01 power supply ATX" ??..

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).

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

Hi interneti et al...
Could somebody tell me the capacity and voltage of the two caps shown? Many thanks in advance!
