convert 1A DC current source to a voltage source

[ariebl]

Hi all
looking for switch mode power supply to convert 1A DC current source to a voltage source (3-12V)
note I can't use linear converter (resistor or Op amp) cause of the high power

What is the source of this 1A DC current? What is its maximum voltage?

 

[ariebl]

max voltage of current source is 12V

as I thought it is not a simple issue: a power switching current to voltage converter...
