 |

Can anyone advise if these LSI chips are common. I believe they are DC to DC converters but I am not sure. I cannot find any information on the web about them. Any info would be appreciated.

welcome to the forum, I have one similar to these but its a 1801A with a date code of 7450. I have never been able to find out what it is exactly. But they are nice looking chips anyway and I wont throw it away
