This thread is for that hard to find information on those chips marked with a year. They are typically used in "no name" brands such as Raptor, Allied, and others made mostly by Leadman.
I was watching a thread .....a member was repairing a power supply with a chip marked 2005. I have looked at those power supplies I have and found chips with the following years: 2002, 2003, 2005, and 2012. I have found that the 2002 and 2003 are interchangeable. The 2005 and 2012 are interchangeable. But the 2003 and 2005 are not interchangeable. The difference is in the function of pins 1 and 6.
In the 2002 and 2003, pin 1 is Vdd power, and pin 6 is the 12 volt rail voltage monitor. In the 2005 and 2012, the pin 6 is changed to Power_good input, and pin 1 now has a dual finction of Vdd and 12 volt rail voltage monitor. This dual function works identical to the TMS7510 supervisory chip.
I am including a pdf chart showing the pin outs for these four chips. Also a datasheet for the ATX-2005. Be careful, the ATX-2005 datasheet matches the 2002 and 2003, but is incorrect for the 2005. It is also possible that there are two versions of the 2005 chip.
