What is the part # for the IC chip on the a1370?

I have identified the IC chip on my motherboard and I would like to replace it. When I try to purchase it I found that the LP8550 chip has several versions. Which one is the right for this model? Does anyone know? or are all LP8550 the same?

Why do you want to replace it? Every time the manufacturer makes a new batch of chips even though its the same they change some of the numbers at the end.

Geekygirl, check the datasheet right here. Looks like straight LP8550 should work
