kbyrne Posted April 28, 2011 Report Share Posted April 28, 2011 http://www.electronics-lab.com/forum/index.php?action=post;board=13.0Newbi needs assistance with a DC-DC Converter kit that is defective in the requiredIC calls for a CD4001 with 14 pins and the board has only 8 pins. I desire to redo the board as it is deffective but do not have a schematic to work with only a parts list and a two sided board. What to do next. Any help would be appreciated.

kxenos Posted May 23, 2011 Report Share Posted May 23, 2011 Probably the IC that came with the kit is of wrong type. (probably someone equally unlucky will have a board with 14 holes and an IC with 8 pins, and his kit also won't work). Try to google every code the board has on it in order to find the manufacturer and send them an e-mail. :-)Konstantinos Quote Link to comment Share on other sites More sharing options...
indulis Posted May 26, 2011 Report Share Posted May 26, 2011 What makes you think the kit is defective? Does the parts list agree with the PCB? Do the parts in the kit agree with the parts list? Quote Link to comment Share on other sites More sharing options...

kbyrne Posted February 12, 2012 Author Report Share Posted February 12, 2012 Just a final note from the author: I redid the board with a 8 leg IC Part # ua741 and project is complete.The board was redone in Eagle only one sided instead of origional two sided type. It worked the first time out. Thanks for assistance to all. Quote Link to comment Share on other sites More sharing options...
