"reverse" engineering - of sorts

Hello all,

Is there any way of finding out which of the LNK623-626 chip is being used in an auxiliary psu.
No, I don't have the schematics and yes of the LNK-something, just the pins were left on the PCB, the rest is
kinda "vaporized"...

Hi Inch-o, I'm afraid that it is difficult to tell which part it is based on your description of the situation. Perhaps if you knew the power level of the design, you could make a guess based on the family power table. -PI-ODO
