    I want to design SMPS under below specification-

    1. Input - Universal 85-265VAC, 50Hz
    Output- 24V@3A


    2.
    Input - Universal 85-265VAC, 50Hz
    Output- 36@3A

    Buy one. It will be cheaper and faster plus it will be reliable too.

    Agreed- buy one.

    The design of a good SMPS is a non-trivial effort.

    I don't know how you can say that. We have tried to give you the best possible advice. You can take that advice or ignore that advice as the mood moves you. It is however rude and disingenuous to complain that nobody is interested in your post. If you were an accomplished circuit designer and had awesome technical and construction skills then perhaps your goal of constructing an SMPS would seem more reasonable. If you still want to do that you're going to need to learn a few things and you're going make mistakes that result in producing magic smoke.

    Well if you want help tell us what you are using it for and why you think it that needs a specific custom power supply otherwise if all it needs is a 24-volt source that can supply up to 3 amps then a common off the shelf unit will work just fine.

    Lack of sufficient information on your part leads to lack sufficient replies on our part. :rolleyes:
