Hello everyone I'm collecting ideas, plans, projects, tutorials, appliction notes etc ... to make a dcdc block which I give the specific in figure below

I'd like to be able to adjust the maximum current.

Could you help me advising for example pwm controller to be used (Texas, Linear, ...), the method by which to adjust the current and the configuration best suited to achieve my dcdc (forward, flyback, puspull)
For now, consider the purely resistive load.
thank you very much

 

You have to be a pretty slick designer to do both at once. Are you?

The usual way is to make the voltage converter and add a current regulator on the output.

 

Here is one idea.
