    Hi Everyone,

    I am currently looking for a DC-DC buck-boost converter for my project, and was wondering if anyone has any suggestions as to where to look for such a device. My input is 10-75V and the output is 24V, and I want the output to be able to handle close to 100A over current. Does anyone know where I can obtain such a unit?

    Thanks very much,

    100 amps is a LOT of current.

    Worse, at 24V it is a load of power. About 2.4kW, or 2,400 watts.

    Additionally, assuming 80% output efficiency, at 10V in you will take in well over 300 amps at this output.

    And getting rid of those extra 600 watts as waste heat is not going to be easy.

    This is pretty high power stuff - you're not going to find anything near cheap to do this, if such units exist at all.

    I hope you mean 100mA of current..
