LT3080 High Current Equivalent for 4 channel bench supply

<< < (3/4) > >>

coppercone2:
Are you sure the circuit in the data sheet does not work?

The zener diode should limit the voltage drop across it, the thing floats anyway, so the output does not care what is going on other then in the input. If you look at it, there is nothing connected to it other then capacitors.

 I am on vacation tho

... and this is why a quality bench power supply is not inexpensive.

FotatoPotato:
I guess so, if you want the quality then you gotta pony up the cash for it  :-//

FotatoPotato:
I think I have set my expectations a bit to high because 48v is just gonna cause unnecessary hassle, I think for the high voltage outputs I’ll keep it at 30V and just pump up the current to like 6A per channel. Other than that I just need to figure out hot to change Daves design to allow the greater voltage output and current output adjustment and I should be good to go. Fingers crossed

coppercone2:
that circuit should work. I figured out how to use gimp so I can get you what they wrote. But buy the book.

you owe me for this because Gimp IS FUCKING IMPOSSIBLE TO USE JESUS CHIRST

BUT THAT one can do 1-500V
