Hello,

My customer looking for isolated DC/DC with the following properties:

  • Input power: 10V DC ~ 30V DC (can be less than 10 and higher than 30)
  • Output power: 100V DC (+/- 5V)
  • Max Output current : 10mA
  • Isolated

Hope that someone can advise. 

regards,

Shahaf

    Hello Shahaf,

    I will recommend using the Power Stage Designer tool for this application, this will give you a very good idea of the power-stage in detail. You can play with it by clicking on each element and scroll on the input voltage and Load current to see how current and voltage waveforms behave.

    I have attached the file to download the PSD and the Boost_exam.txt (please open in PSD tool) file with your specifications in it.

    I hope this helps.

    Regards,

    Sonal

    Hi,

    Can I ask what version of windows you are using? Also, did you follow the steps mentioned below:
    1. Save the zipped file.
    2.Unzip the file.
    3. Run the Power stage designer .jar file
    4. Save the Boost_exam.txt file.
    5. In PDS tool click File<open<Boost_exam.txt.

    I would also like to know what do you mean by tool not working, can you not open it?

    Regards,
    Sonal
