    Hi
    I am looking for 33V boost converter.
    Min output current = 300 mA
    I found this design, but not sure about it.
    Please help me.

    I also like to use different circuit. Please suggest me a chip or circuit.

    Thanks

    About functionality.
    Before I make PCB i want to make sure the design.
    Will it produce 33V and about 300mA current .

    I tried to find alternative chip but it was not easy.

    Thanks

    Have you looked up the datasheet for the TL594?

    The 2N3906 is good for 200mA max, so you'd need a higher rated transistor.

    I'm not sure what purpose that transistor serves.

    Yes. Transistor for on off. Yes I looked the datasheet.
    But I don't have so much knowledge to confirm the design

    Hi
    I am going to design 12v to 33V converter.
    I chose LM2585
    will it work?
    I am going to modify this circuits.
    Please help me, I am not sure about the selection.
    200mA current is enough at 33V output.

    Thanks
