ADP2387 vs ADP2389

Search in electronics distribution led me to your part ADP2387 (my application needs 12V in, 8.5V/5.5A out adjustable high efficiency sw regulator with programmable current limt), but when I do same search on your website your ADIsimPower tool points me to your ADP2389/2390 part and the ADP2387 part doesn't show up at all.   I'd pick the ADP2389 part, but I don't see any of this part in distribution.

Questions I guess are why ADP2387 doesn't show up in ADIsimPower tool, and how can I purchase ADP2389 or 90 part in less that production quantity.

  • Our latest search tool with results showing ADP2387 is found in this link: www.analog.com/.../11472

    ADP2389 can be bought through Digikey and Mouser but currently no stocks. They show lead times though. If samples are urgent, you may contact local ADI sales or FAE who may be able to help you.

  • Thank you for the reply.  My question was regarding your ADP2387 part showing up in your ADIsimPower tool, not the part search tool.  Supposedly the ADP2387 is supported in the ADIsimPower tool but it doesn't show up for me.   

    Understood about sampling.   Being a small company, preference is given when selecting a new part to ones which appear to have some user base, and one indication of this can be seeing stock in several major distributors.  The ADP2387 appears readily available right now now while the ADP2389 does not.

    Because of these issues I have elected to go with a different manufacturer/part for my application.  Thank you for responding to my post.

  • I'm sorry If I had not understood the question properly. I want to emphasize that for whatever part you go for, we are willing to extend support.

    If you can tell me what is your product Estimate Annual Usage, I can give you demo board that you can try and modify to your design. You may want to send this info and mailing address to me at fil.balat@analog.com
