    Hello everyone...

    I got confused in my project power supply section...

    I made one sliding mechanism project in that i use 0.5A stepper motor. At the place, where i want to use this project has only source of electricity is battery bank of 52V.

    voltage and current rating of my project i measure 12.00V and 0.600A.

    please suggest me what kind of regulator i should used. suggest me any link...!!

    You need a 48V to 12V step down dc-dc convertor

    Why did you title your post "regulator to obtain 2.5 amp and 15v from 50v" instead of "0.60A and 12.0V from 52V?

    Anyway, I think it would be hard to find the solution ready built for you. The LM2576HV sounds like a good solution but you will have to build the circuit shown in Fig. 1.

    After about 5 minutes of web searching I found several suitable regulators.

    Anything you build will be more expensive and less reliable then something you buy for the intended purpose. (Anything *I* built would be the same.)

    Nevermind. Should've looked before speaking.

    I wholeheartedly believe in BUY instead of BUILD, when and if you can.

    I don't know; I have seen some pretty crappy assembly, soldering, and layout on "factory built" electronics (even at some factories owned by US companies I worked for.) Now, if you are comparing homemade with the best manufactured products, maybe I would agree on quality, but then the cost advantage comes into question.

    You can get simple switcher demo boards cheap a lot of places. Try ebay.
