    Constant Current Driver Design (Also, i'm back :) )

    Sorry about the confusion. The implementation I have is in LTSpice, not on an oscilloscope, which means I can easily view the (theoretical) ripple current, although this would be difficult to do with a real circuit and scope. The voltage ripple on the output in LTSpice is only a few mV!

    Constant Current Driver Design (Also, i'm back :) )

    Thanks for the feedback guys. Just one last question. Is there a guideline for the maximum acceptable ripple in the output current? I am currently testing an implementation using the LT1074 that seems to be performing well in simulation with a 60mA ripple @ 4.5A (currently working on reducing...

    Constant Current Driver Design (Also, i'm back :) )

    I'm using this as an exercise in circuit design. Just buying one would defeat the purpose :) I saw an open source design that uses a standard buck regulator with a current shunt and current sense amplifier going back to the ref/sense line on the buck IC. It seems like this is the route I am...

    Hello LPF, long time no see! It's been a good long while since i've been on here. After switching my focus to multirotors and FPV and then moving to the east coast for school, I seem to have forgotten my roots! Well, 2+ years later i'm halfway done with my Electrical Engineering degree and...

    Hello LPF peeps! Long time no see.... As some of you may or may not have noticed, I haven't been around much! I do miss you guys, though! I seems that I have transitioned to FPV quadcopters now. I have myself an emax 250 quad and a goby 210 coming in the mail (all built by myself, of course :)...
