DC CC 9A 280W Step Down Buck Converter 7-40V To 1.2-35V XL4016 Module (tested under 12V)

Hi Robojax, I just bought one of these XL4016 modules, hooked it up correctly, applied 6 volts to start and started turning the voltage cw. The red light came on right away and the voltage decreased from 4.8 to 2.9 and stayed there. Turning voltage and current pots either way does nothing, stays at 2.9 volts with the red light on. Gave it 18 volts DC and still nothing. Any ideas?

good💯💯💯💯💯💯💯💯💯💯💯💯💯💯💯💯💯

You have to state what are you testing, either your power supply, buck converter, your load or yourself!... can not see your power supply, is it a battery 7AH 12V battery or a simple pack of Li/Ion battery?....

What's the source voltage and current before the Buck???... That might be the failed current voltage source on your part!... Try using a source of 20V and 10A so we don't have to look back on tests...

Can I use 24v input with 6a 100w for this module?
RESPECT🙋‍♂️

you cant go above 5a at 4v as amp increase so as voltage

Thanx for the video my brother..what would be the result if input is 24v and output 30V set at 2A...Thank you

Buenas yo tengo este modulo para cargar un bms s6 de 24v el adaptador que uso es 12v 4a y lo elevó a 28.5 porque tabien tengo un mini amplificador de audio que soporta 30v ago mal subir al bms s6 28.5 normal mente lo tengo 🔌 el altavoz 🔊

what the meaning red lamp on the step down?

What happen if you remove the insulator paper betwin XL4016's and heatsinks? Thermal transfer should increase

Like. I'm using one today on a Ryobi 18v One+ charger. 2nd build, this time with a 24v xfmr stepped down to 20.5v using the XL4016. I tried step up with a small 12v xfmr but could only get about 90ma. Your video gives me confidence, I hope I don't die.

Got one of these units, but current is at maximum, cannot adjust. Had a look over the board but nothing stands out. Any ideas?

Obrigado pela explicação, este módulo que protecção tem? Do gênero, curto-circuito, inversão de polaridade, etc. Estou a iniciar eletrônica e queria construir uma fonte regulável de bancada. Obrigado

Good day sir! I would like to ask if I can use this on my 3pcs 12dc fan 15watts each with Direct to solar PV set up? Currently my set up is 100w solar panel and 3a mini buck converter each fan between solar panel. Am planning to use this DC CC 9A 280W Step Down Buck Converter for my 3 12vd fan instead of 3 3a mini buck converter. Will it work?

Hi, Can I use this module to charge 12v UPS lead acid battery?...

Please what is the machine with fan where you put the amperage you want?

If you limt the inrush current it will go 9A.....current peak on startup is too high....

google faz o idoma ficar fixo.(para google) EM PORTUGUUES PARA MIM.

is this still the best one to buy in 2021?

Hi, what is the name test to voltaje and current?

great video.

Can i use this converter to run 12v 7A water pump continuously 7 hours?
The input sourse is 24V 130Ah battery.

Hey Sir ! Can I use it in 24 volt power supply to make (1.25 - 24) volt 9A power supply

Thanks for the video. I had a problem in 2 of 10 boards that a bought, I have set them to 8 amps and after 1 day working it stopped, and both where limiting the current to les than 1 amp. And the voltage regulator was working, the only problem was that they were limiting the current to less than 1 amp, and the current control was in the maximum. Very strange thing, I think that the IC may have burned.

If you calculate faster, will it pass 😂

Nice video, so I can consider to buy this module👍

Thank you so much for your time

Hi do you think it will work at this voltage
Input 16v output 12.6v@6a because
I will buy one

Good test,thanks it is very helpfully

touching all those components with your screwdriver while you are explaining makes me very nervous. But great videos as always. Thanks a lot!

Thanks for video. I have a question. I build (DIY) solar panel for a project 12V/5A . I want to regulate output voltage to 9V/1A for other devices . Do I need diode between solar and this XL4016 module to protect solar panel from returning power.or not.

Does anyone knows if this buck converter can adjust a current as low as 20mA? thanks a lot!

Can you explain me how to set the current to max 5A?

Thank you for your videos; can you give me idea how to (set step by step) the current of the xl4016 on my power supply. My psu project will be for 3A and acording specifications xl4016 can supply 8A. The psu working good.

Thanks for the tutorial, I have one of these step down buck converters, I would like to use it to recharge a 3s 18650 battery pack (3x sony vtc5a 2600Mha, 35A maximum discharge) I adjusted the output voltage to 12.6V and the output current to a tenth, 260 Mha, when I connect the battery pack, the voltage (measured with the tester) drops drastically, is this normal?

Thank you

Why does it shutting down?
I have the some buck converter and it can easily do 9A forever with cooling fan.
You might have a defective one.

I used it with power supply of 12V, 5A and output 5V in order to charge 18650 cells and it couldn't handle 2A.. the first cell was charging fine at around 1A but when I put a 2nd cell it only provides around 1.2A... and even the leds are struggling.. maybe I do something wrong??

Can I use 36v and 6amp adapter and get max power ???

great lesson I learned. there is another Vidio discussing about the PWM signal in the Buck converter?

then can it bear a load from 5V to 9A? I need to connect a motor with those parameters

ty nice test

Is lm2575 suitable for xl4016 buck converter? Thanks hope somebody answer my question thanks

What driver is used for the mosfet

some seller really be lyin and is now exposed by robojax lol

simple, easy to understand even for a noob like me, really inspiring, i wanna be like you someday.

Many thanks ❤️❤️❤️
