I have this cheapo sfx power supply with offline switcher marked ME8117 and I can't find it's replacement in my country
Here's its datasheet
It's pretty much chinese
OB : external starting resistor/ starting current input
OC : output to transfirmer
IS : switch current sampling & setting limits, external current sampling
I include drawing of my power supply schematic in those me8117 area, and its quite different from datasheet typical wiring, lol.
My psu use sc6105.
+5v standby it's okey
Can I somehow change this offline switcher with tny277 or any common ic? I kinda afraid how it's wiring, connecting where to where
Tny277 only need 4 wiring right?
En to collector opto
BP to emitter opto with cap in series
(what's the cap value?)
S to emitter opto
D to +AC with snubber network
(what's resistor and cap value and what diode?)
Please help me guys
Pleasee
I really appreciate it
Thank you
I made the same thread 2 days ago and no one replied lol
