How to power multiple LED chips using single driver and several DC-DC CC converters
If you have a 600W, 36V LED driver circuit available to power 5 100w, 30-35V LEDs, why would you then need to use voltage converters?

LEDs actually don't care if you apply a source to them that is capable of an open-circuit voltage over their rated voltage; they only care how much current you allow through them.

This means that all you really need is a FET for each LED &amp; a resistor/zener diode to set the current passed by the FETs in order to drive your LEDs from that 600W, 36V driver (or from any other 35-38V source that's capable of pushing the needed 15A). Something like this should work great:
