I am building a laser engraver, the current setup uses a 12vdc buck to drop to 5 vdc @ about 6 amps.
It uses a IRFZ44n to switch on/off the 12 vdc input to the buck.
I want to use a variable input 0-5vdc I am sure only a few milliamps, to be able to vary the laser power by varying the buck 5 vdc output
I have been searching like crazy but not finding anything premade that I am aware of.
Can you suggest anything ready made, or suggest where i might go to read up about building my own.
