Hi
This TI note says we can parallel the LM2587.

Is it safe and functional to parallel these off-the-shelf buck modules?

i'm wondering, if their voltages are different, then the higher V will try to dump it's extra into the outputs of the lower V, which seems bad. Maybe could prevent with diodes?
thx!
