# Identifying an IC with markings: 0270000 DCP1227 0601

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?

• I think an image of the component would help identify it. – alexan_e Mar 30 '14 at 23:00
• Thanks, I just added a picture. Its from the side to make both the markings and the pinout from the side available. – KingsInnerSoul Mar 30 '14 at 23:31
• BTW, I suspect it to be a Burr-Brown DC converter. But I could not find this exact part number in any datasheet. – KingsInnerSoul Mar 30 '14 at 23:34
• What else is it connected to? – dext0rb Apr 2 '14 at 20:44
• What's the board it's on? – Passerby Apr 2 '14 at 23:31

It might be a custom IC made just for the company whose board it is on. I ran into this once without realizing it. I made an educated guess about the manufacturer, and even called them up for help. Their response was something along the lines of "This is a custom part for one of our customers. How do you have it?" I don't remember what I said in response, but I ended the conversation quickly.

• I find it hard to believe that they have the $power to request a special design IC. I just do not see them having enough income to request something like that - after all, changing a mask alone costs several$k's... I dont want to remove the part as it does not have "leg" pins. Its going to be hard to take off and put back. – KingsInnerSoul Apr 3 '14 at 13:35
