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!

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...

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...

Ah yes, not in the description. Its a 445nm :)

:bumpit:

Actually the labby is still up for sale! :bumpit:

laserBTB 445nm 2000mw SOLD!

Great to hear you like it. I forgot to PM you that I was going to throw in some batteries for free :) No one wants any beautiful 445nm photons?

Re: KRNAZNBOY's House Cleaning Sale Yep, 532 has been sold! Still a great deal for those who want a 2 watt + 445nm Handheld firestarter :D also, the labby, a great laser to keep on your table, will work well for laser shows too..

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 :)...

Much clean, very power, such cool, so wow +rep

:bumpit: need to sell the labby please!

:bumpit: last stuff to go please

:bumpit: prices dropped for the final time

Its some weird guy from a cooking show. Hes flapping around a tortilla XD :bumpit: Pls bois

:bumpit: misc lenses and red modules sold! Updated OP! Need this stuff gone bois
