Post by thread:[OT]: Need help to find a Chip producer

Hi Piclisters, Sorry to post this OT query, but I did not find my info on the web, and I hope some Asian Piclisters are reading this and can help me. I got some used Switched Mode Power Supplies (SMPS) built in Taiwan, and want to use them to power some projects. These SMPS, from Asian Power Devices use an 8 pins DIP controller which reference is KA3843C. My questions: - Who is the producer of this KA3843C ? - Where can I find a cross reference list and/or producer list of asian semiconductors? - Is there any Search Engine, in English, more focused on Asian Market than Altavista or Lycos ?

Hello Gerard, this sound to me like a similar part by signetics, called SG3843, there is a complete family of SMPS controllers. KA is the usual Prefix for a Samsung device, so you could try out your luck on their site, too. I don't know the site of Signetics as of now (after several takeovers), but looking for the "forefather" SG3524 will lead you to the site, I believe, and the sites of other manufacturers. This IC seems to be a common type, at least to me.

I think KA is usually Samsung. This part number sounds like it may be equivalent to the UCxxxx series of PWM devices made by people like SGS-Thomson and several others Try a search for '3843' on http://www.findchips.com >- Where can I find a cross reference list and/or producer list of asian >semiconductors? >- Is there any Search Engine, in English, more focused on Asian Market than >Altavista or Lycos ? http://www.google.com is usually a lot better than the above search engines. -- http://www.piclist.com hint: To leave the PICList piclist-unsubscribe-requestspam_OUTmitvma.mit.edu

Also, try Unitrode (now TI) who have a UC3843.
