Hi:
I am trying to repair an ATX power supply, where "everything" blow up.
- The Fuse
- The Diode bridge
- the 2 "mosfets"
I would like to ask you about the "mosfets" because when I look for the reference 13009 they seem that they are NPN transistors. (hopefully attachment is inserted).
2+1 questions I would like to raise.
- Does the brand that appears on the chip looks familiar? it's not ST, right?
- Are these NPN indeed?
- With all the listed casualties. From your experience......anything else to look at? PWM chip?? (schottky diode are ok).
Thanks in advance,
Francesc.
