Hi all, I have some old ATX PSs here that I would like to modify and use for other purposes but the problem is they don't come with the well known 494 chip but rather with something called "2003". I have found a similar schematic of the PS, but without the IC datasheet I could not do anything.
I have two identical chips here, named 2003 with big font, and on the other row there is "IFFNS00247E" and "BAQ11420423E" for the other one.
Can someone give me some hint where to search, as googling 2003 as obvious gives nothing for an IC. How in the world you could name an IC as a year's number? I have read some other people also asking the forums about this but with no result. I guess this should be not so big secret as PC PS are made with it.
Thanks, Todor
