    Hi
    In MAX1747 datasheet, there is the montage in the picture above, everything is clear with the values and everything, only those diodes I don't understand what is their role, also they put them without any information about them in the datasheet so I don't know how to choose them, anyone has an idea about that?

    You just didn't read far enough. ;)
    They are mentioned on page 12 of the data sheet (Rectifier Diodes).

    The diodes with the capacitors form a voltage multiplier ( 3 × the input voltage ) The voltage is controlled with the feedback circuits inside the IC.
