Can you take the actual image? the link image above is not clear but if you have a phone adjust your rear camera to high settings.
Must be this
Then take a picture of the board focus on the "boost circuit" if you can't still see the exact model of that IC try to clean that part with alcohol or thinner and take a pic again.
If it's still not clear then you might need magnifying glass or microscope.
I tried to search all of those numbers in Google and most chips that I found are 4 pins, not the 3 pins.
