Hello Ugochukwu anyoha，

We are sorry it may be hard to make one with such large output current.

And most of voltage converters can’t decide how much current the load should draw. They just give a limit on output current. Assume output current can be controlled by  tachometer, that just change current limit value instead of actual load current.

Best regards.
