Hi,
Please consider the buck-boost topology.
It could get a negative voltage.

I am not sure what are you talking about?
What do you have now? Do you have the schematic?

sir,
i am having TPS40210 DC-DC converter circuit. that gives variable output 60V to 100V. So now i want to split that voltages into variable +-30 V to +-50 V.

Hi,I don't know how to.
I suggest you repost your question into the non-isolated DC/DC forum, there are more experts on this part.
