the other side of the cap is ground . - you can see the vias points connecting the bottom side. I am pretty sure I have sent you the correct wiring pads. the diode you have has a dirty window or a dirty lens ;)

nice reflowing work Kent, let's see how you fire it up :D :beer:

Kent, I like the Serial Diode Killer title :gun: - you should change your nick name :D :beer:

aaaaaaaah man that tube is so cooll man..... Wanna wanna wanna :D :bowdown::bowdown::bowdown:

:beer: I know I just pointed that one ben boost wouldn't handle it :D Didn't want to let the OP think a single ben boost can do 1.8A :D

yeah, ben boost can only handle 1.25A max, he would need 2 x benboosts in parallel to get that 1.8A

actually the position of the waveform on the screen is a little lower than Zero that's why you read it wrong if you count the dots you you will see that is practically the same :D

Ben, 22uF is pretty enough I guess for the ben boost. I just stacked the other 22uF on top of this one making the output cap 44uF as you mentioned. See the results: 44uF Output Cap compared to 22uF output Cap Just what I expected. The extra cap did absolutely nothing. The ripple is the...

thanks man :) :beer:

what am I up to? I don't understand :D

thanks :beer: I try :D

my next revision is ready. I wanted to lower the ripple to 10mA max but I had some problems similar to the ben boost when a cap is added between Vout and FB so I had to remove it.. Increasing the output cap showed no further improvements. But there is a ~70uF capacitance at the output. And 44uF...

almost like a lightsaber prototype :D niceee

I will try it tonight Ben :beer:

ok I did my tests on video and pictures this time instead of just my word for it. :D I made two identical setups of the ben boost but on first tests we have 22uF cap between LD+ and LD- (Vout and FB) on the second test we don't have that cap. Input and Output caps are both 22uF on both tests...

Chebyshev Pi LC Low Pass Filter Calculator here is a PI calculator, somebody can figure it out maybe? :thinking: :D

that sounds good but isn't the inductor supposed to be able to carry the output current. that will result in larger inductor and will take a lot of space :? or am I wrong :thinking:

If you need 2A maybe you should go for the blitzbuck. I am not sure how many amps the X-Driver can handle

I think we need a resistor and a cap in series. Paralleled to either Vout and FB or FB and ground.... But at what values is a total mistery to me :D.. I also tried adding more than 200uF at the output on my driver and there wasn't any change at all :D and btw does somebody knows what kizdawg...
