Dear Sir

I have a 12A  output current application, i want to use more LM3409 device  output parallel. Does this solution have any risk?

Thanks!

    Eric,

    In general you can parallel the outputs since you have a constant current output (high impedance). However you have to note that there will be no frequency or phase synch between the two, and they may also have current mismatches due to the current sense variation from IC to IC - so they may not share currents equally.
