Just did a search against a schematic that uses the "2003" Ic, it appears to be a custom-made IC. Comparing the pinout function of TL494/KA7500 circuit design does NOT match with "2003" IC . The "2003" chip appears to have several additional functions. http://techlabs.nm.ru/JNC_LC-B250ATX.gif "2003" chip used" The TL494/KA7500 is definitely NOT the same http://focus.ti.com/lit/ds/symlink/tl494.pdf http://techlabs.nm.ru/codegen/codegen_250xa1_cg-07a.gif |

|
| I have an ANS LC-B300ATX psu at my workbench, the only IC i could find is the one with 2003 mark on it.
I wonder if somebody could tell me the function of the IC which has a big 2003 mark at the top and under it is an alphanumeric numbers which i found out was randomly marked ( that means same 2003 marking but different alphanumeric numbers under it on same brand IC). I don't know if it is a combination of the tl494 and lm339 sort of ic in other psu. |
