Hello, I am thinking of replacing the damaged charging IC on my Archos, but I can't find the right chip, i.e. the MC34063A. I can find chips with names like it i.e. the MC34063AP, MC34063ADG, MC34063ABD etc. but not the exact one, and I can't really tell the difference. Should I be looking for a chip with a certain output, i.e. 6 volts?
