Re: Need to identyfy IC

Since there is a '=' in the markings, this means it is from Richtek.

The hunt should be for 'QR=' since the 8K = datecode for the mfr of this batch build and is not relevant for the replacement.

You are quite welcome. In reviewing your location, looking forward to visiting Sangeetha Veg restaurant (one of my favourites for their thali) in HK next week - the countdown begins for the assorted electronic fairs and shop till I drop. Will review the Apple repair scene in Shenzhen. Time for some strong coffee.
