    i need a Switch Mode Supply.specification are given blow

    Input voltage 220 AC

    Output voltage 12 DC

    Current 10 A


    plz give me the circuit diagram of the above specification and one thing is important that this is a Switch Mode Power Supply.

    Are you sure you want to go down to 12vDC?

    If this is for your streetlamp design, you will be better served using a higher voltage for those 800 leds. Even jumping to 24v would be much better.

    ok brother

    i will try to use the 24 and change the circuit

    now plz tell me the Schemetic diagram for

    input 220VAC
    output 24VDC
    Currect 10A


    must be a Switch Mode power supply

    I would have to agree, Rifaa. I would also go for 36V..at least. I was doing a little fumbling with his idea, and I am finding that a 48V supply would be optimal. He would save money with the gauge wire to use in the project and the leds would be happier longer. He wants a schematic for a smps at these voltages, but I am having a problem getting one together for him that he can get in Pakistan. Any ideas?
