What is the best topology for DCDC power converter

What is the best topology for DCDC power converter with the following specs:

DC in, min 30V, DC in, max: 110V, Isolated Output: 15V 10A

Hello,

In general for DCDC isolation, I think a flyback could work. Here is information on this topology.

For 150W power, you could refer to our ACDC flybacks.
