LED Dimmer

I seriously doubt you will find a pass through unless you build it. I've not seen a board that is a real buck/boost in the literal term. You could always install a boost board to 20v (or whatever), then back it off with the board above. Those boards are so cheap it's fun to try different ones and combos
