I see above solution but This Solution is not meet our requirement.
I say I have need one solution and I can use solution as per my requirement with same switching IC.
Example- I have select one switching IC(UCC28740)
When I have need Input Voltage-80VAC to 264VAC/ 75VDC to 400VDC with Output Voltage- 5V/2A.I can assemble component as per design.
When I have need Input Voltage-15VDC to 60VDC with Output Voltage- 5V/2A.I can assemble component as per design
I think you should try UCC28600. Because of 15V startup requirement (startup threshold is 13V of the IC).
We do not have reference design exactly for your specifications. But there are a lot of designs available based on UCC28600.
