Some of you might use an XL6009, and overload it as it's current spec isn't 100% accurate. If you do overload it, this is how to repair it and enhance it at the same time. - แนวปฏิบัติและการใช้ชีวิต

Your kid was so cute, I hope she/he is still good in 2022! :)
The diode testing setting on multimeters shows the diode forward voltage drop in millivolts, not resistance. A normal silicon diode will show about 600-700mV and a Schottky diode around 250-350mV.
Also you won't double the current capability of a diode by using two in parallel. Their forward voltage drop has a negative temperature coefficient, so whichever diode gets slightly warmer than the other will pass more current and that will heat it up more until it is passing almost all of the current while the other one passes very little.
Perfectly correct. It is somewhat like putting two relays in parallel. A sudden surge current could cause one contact to weld at any time.
you are right but they are pretty close so I think it might actually be a good idea since if one of them heats up it will most likely heat the other too so no problem
not sure tho didn't try it just my thoughts
@@mahmoudsalah7628 It's a nice thought, but it just doesn't work. You might be able to increase the current capability of a single diode by a small amount by putting two in parallel, but you'll never get close to doubling it. The same effect makes it complicated to try to parallel two power BJTs (you usually have to add an emitter degeneration resistor to each one).
The datasheet recommends and 1N5824 diode in its typical application circuit, also as it isn't a smd component it will allow more heat dissipation.
I had the SS24. I replaced SS34 with SS24 and it worked again. Thanks a lot for the video.
Happy Birthday :)
great to see an old antex xt25, my first iron
Thank you Antony, you are a great teacher. I enjoyed your kid. Shalom
Thanks. I repaired my module using your method. Only difference is that I used a thruhole diode to allow it to disapate more heat. Worked perfectly.
hey. can i use regular 0.7v diode on my buck boost converter? the diode on my buck boost converter smoked when i connect the polarity of my power supply reversely.
Thanks for the video dude. The problem I have is there is no output at all and a red LED is on in all of my 5 modules that I bought recently. What's the problem here?
i used a 12v dc fan and used xL6009 booster module. for input i used custom li-ion powerbank. on setting voltage to 12voltage, the fan speed is not par as it should be, it increases but not as it ahould be. and n while fan is running, voltage shows at 4 or 5 volts on display..
what could be the reason, little help will b appreciable.
Thanks you helped me resolve the problem
Thanks! I know where to look if the board stop working, and nice piggyback the 2 diodes together 8-)
Excellent video, thanks! Encouraged me to repair mine except i switched out the SS34 for a SS54 to get the extra current and it works great again now. Also, i would advise the addition of a small adhesive heat sink on the chip helps it a great deal. Mine works fine now up to at least 3A.
englishrupe01 wow, that's great!
Sir is there any possibilities of controlling of output voltage without rotate the knob using pwm Arduino..
Thanks alot for the video sir, i was not have the same SS34 diode so i soldered three SS24 diodes. Now my module is working fine.
so, i can do this technic for rectifier bridge also... right?
Hello sir, in my broken boost converter the in+ and in- are shorted. So İ dont think the problem is the diod in my situation. Do u have any advice for my problem? Thank you.
Brilliant! always was wandering why these modules broke on me. Go to try your fix because as a hoarder ;-) I have all the broken modules in my junk box, you know.. could be used someway lol.
Haha, I do this too, so that I can perform an autopsy on them and learn more. It's how I learnt how to fix it! :-)
I got szbk07 300 watt and one is putting output same as input other one shows ver low 160 mv u got any idea and chip is lm5116
X2 diode =/= X2 current flow.
It is not additive but sure pn-junction stabilization with lesser stress on the main load carrying diode.
@2:40 should be your birthday by now so happy birthday ! :D
Haha, my birthday is in November! She was a few months early/late! :-D
This video is good becuase today my XL6009 Boost Step Up Converter diode literaly vapourised into thin air after accidentally the module got short circuited.
how about soldering regular big 8Amp (Non SMD) Diodes on little wire? Should help spread heat too.
bhvm333 That also works. :)
In my xl6009 buck boost converter,I had increased output voltage above 45v and suddenly my display showed 0.0v and some 220mA. Xl6009 was getting very hot as well as the ss34 schottky diode at the output section. Checked and found the diode to be shorted. Removed it as per your method and soldered a SR360 schottky thru hole diode on to the pads. Working great now and i dare not increase output voltage above 30v because capacitor at the output is rated at 35v. Thank you for your video and hope this information will help someone. Thanks again !!!
I bought a XL6009 step up converter, but it only outputs 50V. Tested it with two voltmeters. I also tested inputing 5V and 3.7V, in both cases the output voltage is 50V. The potentiometer has no effect on the output.
Assalam o Alaikum. Can I use this module for 15 to 20 high power 3watt LEDs in series?
What do you think about OKY3498-4
i like the background opera that you have in the video. much much better that what most people put. i thought u were going to put the diodes in series. i would think the previous one broke down due to over voltage and not to over current
John Conrad what background opera?!?! :)
at 5:42 the voice of a little kid singing.
John Conrad Haha! Lara!
I agree John! That is much preferred! 😄🌎✨
Dear can u tell me the diode name and number plz caz my module also give me low current my module damaged by myself caz I give the power my mistakenly wrong way
So the max input current is not 4A anymore, it will be 8A right? well the ideal Amperage if it is doubled is 6A
I have this problem when my output cable is short, when a leave it for a second. And my child told me that the boost convertes is smoky. When i notice, and i see that the ss34 is burning. Luckly a can get ss34 replacement from old broken cellphone charger. And it work fine after a replace the broken ss34
Thnk u sir its work
I have a problem with LM2596 Buck converter, it's totally fresh but suddenly it's not working,
I change the diode but still, it's not working. Now, what do you think?
Try the little capacitor near the output. I have a trouble sama with you, and when i get a guarantee to the seller, they said that the problem is on the capacitor, when i see closer, the capacitor is not soldering well
In my case it automatically goes down vol help
nice!
Can i put 5v input module?
Thise diodes are not even rated for over 40 volts, however it is still working.
It is rated for 40V
Great video, please share more video !!
i have this and it boosts voltage but when i hook say arduino to it ,it dam near puts out nothing. any ideas? could it be that diode in it?
Donald Henke watch this video, it explains that the diode isolates the inductor coil when the transistor opens the switch:
th-cam.com/video/vwJYIorz_Aw/w-d-xo.html
If your booster isn’t delivering power it could be a bad capacitor - just a guess, I really don’t know.
i have the same problem when I give it 5v input it would be the same output it is not boosting, I check the diode and it giving beep sound in both polarities what should I do now? how can I check IC?
Hi Syed, you need to know what the beep means before you continue.
It probably means that your diode failed "short", so it behaves like a wire and is useless as a diode.
What do u sold in the buck ?
I mean to say name from circuit ?
Js Nonny I'm afraid I'm not familiar with the semantics which you are using to form your sentences. :(
What diode do you solder in as replacement? The SS34? And which mounting: SMA, SMA MDD, SMB, SMB MDD, SMC, or SMAF?
Lol your house even the songs is just like mine...
Did you mean you can get closer/higher current through put. Ohm's law still applies. I've not seen a volt and amp booster in the same device... Recently
Sir Excellent Tutorial, I was looking around lot of stuff to rectify or to find troublesome issue with Step Up Module XL6009E1. Fortunately got your demonstration. Could you please help on issue i am facing up.
As i am connected to 5v battery (Its Power Bank rated at 2.1amp) and also 9v Battery with 1amp to step up module and boost to 12v, if i am connected to dc motor all off suddenly it falls to 4v else, shows 12v. Also i have worked with alternative Step up Module MT3608 and the result is end up same.
I am not able to figure out. Why voltage is getting drop all off sudden.
You may need to increase the input current or increase the resistance of the output (by adding a diode/resistor or two in series with your output) to lower your input requirements.
A motor usually will draw more than a 5v USB power supply is capable of creating when converting it to 5v > 12v after conversion and efficiency losses.

Thanks bro I had the same problem, but it's not recommended to solder two diodes in parallel
Putting 2 diodes in parallel is probably unpredictable in current sharing.
Well, I'm not sure about that... Two diodes which are to the same spec, should have the same or similar resistance. Ofcourse, if they are both the same resistance, current will be halved between them. If one allows more current than the other, then it will still be better than just having one diode!
Practically there would be some current sharing which would probably be enough relieve the power dissipation issue. But since the diodes are not on the same die and tightly matched it is hard to predict how much current sharing occurs. Some is better than none. The ideal solution is to replace with a higher rated diode (if you can get it to fit).
R HP I agree! Also, the way I stacked them is not good because the sandwiched one will get more current and also heat and won't dissipate it very well... Still though... Got to be better than one.
Any improvement is better than none! 😋🌎✨
@@DeanTheDoctor Yes, but two low current diodes won't increase the current capabilities by much because of the negative temperature coefficient of the pn-junction voltage. They are likely to be more expensive and more trouble to solder than one diode with twice the current rating.
Thank the youngin for the birthday wish. Mine was the 7th.
Haha! I don't know why she was singing that! :-D Hey Sick Vic, do you have any video requests? Anything you'd like to see more or less of?
S it's working
really dairing removeing it like that. suprised didnt pull trace.
My board heats instantly what can I do..
Did do you have a sister? The background voice?
Charles Murzello Thats my partner and my kids lol.
Literally just bought mine brand new like this
Me too slightly different module but yeah same thing burned out a fan immediately
@@clovenbeast5183 I changed the diode and it didn’t work still so guess it’s fuck I got a second 1 was running fine then all of the sudden the actual xl6009 mosfet exploded so I’ve ordered two this time lol
@@shokdj1 And that's kind of crazy because the second batch I ordered were kind of similar to what you experienced lol
With this module there is a big problem, when the voltage drop at the inlet below 3.3 V, the output gives 40V! Even if the resistor is exposed to a current of 5v
GeneriK weird!
th-cam.com/video/uArobEAm0do/w-d-xo.html
I wondered why I cant adjust the voltage lower than about 20v. My battery is down near 3v. Will have to see if it works at higher input voltage.
It's been said that these modules are only designed for use on 5V and over.
Too much under 4.5v, and they can enter into a fault like state and do exactly as you described. (40v on the output and no ability to adjust the output.)
= )
actually the diode is shorted, acts like a wire with zero resistance
The SS64 should also fit it the place.
you had enough space to use a not smd diode like 1n4007 or more powerful. anyway nice video.
I tried 1N 4007 but it is not boosting. It varies as buck converter around range of half volt
Was that your daughter she sounds so sweet
You could've put them sideways :)
Sadly on every video your voice is saturated or too loud so its clipping... :/
Yes, i've got a gofundme campain for a new camera. The mic is built in.
Are bhai mera voltage regulator kharab ho gya h pls help me
How to change 143C 103W
Mitesh Dhanani What's that?
103 means it is a 10k pot. the 10 is the base and the 3 is the number of 0's, so a 503 is 50k and a 253 is 25k and so on... you can replace it with a full shaft pot. in doubt, desolder it and hook the middle and one of the extremities pins and test it with a multimeter and see for yourself the range of the pot.
I can't help but wonder why you would choose to completely ignore your kid.
Who say's I completely ignored my kid? The video is heavily edited. ;-)
if i do not have ss34 diode can it be replaced with another diode?
Any schottky diode of 40V 3A or bigger amperage, 40V+ 5A it's the best replacement.
