I have a chip on one of my boards, and I cannot identify it. I tried differnet variations of search patterns but I cannot find it anywhere. The marking on the chip are in three rows as following: 0270000 DCP1227 0601
It seems to be 12 pins total, in groups of three pins in each corner.
I am wondering if the reason I cannot find this chip is because the manufacturer was bought out or went out of business?
I suspect this to be a DC/DC converter from Burr-Brown (bought by TI back in 2000). But I could not find any information about the markings in any online document. I wonder if anyone has an old catalog with a table of product numbers and markings of BB?
