Hi i need to design a step down dc converter (not isolated), i need voltage output from 1 to 48V at 40A, ive seen that lm5116 could do the job up to 20A, could i use bigger mosfet or parallel mosfet to go up to 40A with it? the gate peak charge of the lm5116 is 3.5A, is it enough to drive several mosfet in parallel?
Or could i use two lm5116 system and parallel them while monitoring current of each (this seems harder to do)
Ive found other isolated dc dc converter that would do the job but they cost me 700$! id rather developp one since i dont need isolation (will be powered from big solar panel system at approx 50V input
Thanx
