Thank you. I have recently purchased three converters from different places: Singapore, Georgia, Nevada but none worked. Your testing was appreciated.

[@robojax]

You are welcome. I am glad you found it useful.

[@tahamidhossain597]

Appreciate the video for clear and concise presentation. I was looking for one of this and found it but wanted to know how well it works. You explain everything very well 🙏.

[@pinknoiseaudio2220]

Thank you for sharing this video! As we can see, you have tested 101 coil version (100uH) of this circuit, so the result you have got matches the LM2596 datasheet. I.e. for 5V output, it should deliver maximum 1.3 A at 37V input, see tables at page 20 in the datasheet! This chip LM2596 is not suitable for large input/output adjustable power supply, read the aplication implementation theory, especially inductor selection part. If someone already bought this module, as I did, he has to replace the coil according to his particular application. As an example, for 12V input and 5V 3A output, the inductor has to be 33uH rated at 3.5 Amps. So, the module will deliver 5V/3A and most important it will do that at more than 90% efficiency!

sir good day can i used this lm2596 module.5v input to 12v output 3A.

[@UbaidKhanyousufzai]

When I am doing 12 volt input and set 3 volt on output but digital display is showing 5 volt ie whatever voltage I set it increases by 2 volt but checking with meter output voltage meter But it is showing correct only on digital display two volt is getting high how to solve the problem

[@bymontolla1684]

Hi, mine show a correct output on the multimiter but when i use/connect it to a device it drops to 3.5 v for some reason, I think it needs like a diode or something so the device current doesn't affect the "converter"

[@robojax]

Hi, your load must need more current that this can handle so the voltage is dropped. try it on another load. for example test it on 1A load or 2A. if it doesn't work with 1A, then the module is bad.

Hi, we just know voltage and current. You should know the capacity of the battery and maximum charge amount . Then you find the right change module.

[@OldesBlabLa]

My device is showing output like 5v but when I measure it.. it gives same voltage as an input 12v.. can i fix it somehow? Also the potenciometer has no effect.

[@robojax]

Pushing the button will change the display voltage (input and output). Potentiometer is multi-turn. So turn it it at least 7 to 10 turn before you see affect.

[@officialhonorupdates]

Is it effective for 4.2v input and 2.4v output 2a

[@jeffreycashen6416]

I just bought 2 LM2596 boards and they only have the 1 button on them to switch between in and out voltages. Is this a concern or possibly lesser or greater version of the one you are using in this clip ? And yes, it is always good to research on the type of board and what it can handle.

this is Buck converter (step down) and you should always get lower voltage at output than input. Yes something is wrong with your module.

[@zainabmohammed7501]

If I connect a fluctuating input DC to this buck converter, will it damage it, bcos I want to connect it to a solar panel, and u know V from a solar panel do fluctuate depending on sunlight, thank u

[@robojax]

this device outputs contestant voltage meaning if the input is fluctuating withing the range it will keep the output steady. Sure. but it will not boost it. for example if you set the ouput to 10V and input is between 11V to 20V it will work but if input goes to 9V, then the output will be below 9V.

[@SantaDragon]

Is the LM2596 not also a step-up converter? Why not tested this case?

[@flatisland]

I don't think so. I just tested mine (without display) and the output voltage drops at a difference of about 2V higher input than desired output. Also the data sheet says something along the lines of "the input voltage must be 1.5V higher than output voltage" although that's translated Chinese, so no guarantee. So it's rather a step-down module, not a step-up module.

[@Bergwacht]

i pushed this under 5 volts, now its broken. what part i have to replace ?

[@robojax]

this is very bad design. if certain voltage harms a device, it shown not allow it. repairing would be so expensive, it better buy another one.

I had a same module and i accidentally reverse the polarity of the wire in the input side, the diode burst up. And now trying to fix it if i can still use it. Hehe.. Any hint to find the short. Thank you.

[@robojax]

most probably it is dead. This module has two portion. the regulator and the display. it seems both or one have been damaged. I just looked at datasheet for LM2596 in here www.ti.com/lit/ds/symlink/lm2596.pdf there is not mention of reverse polarity protection so you should think of getting another module I belive.

@@robojax thank you sir.

[@norviniinasol7993]

Update sir, good news, after replacing it with a "M7 diode" . The LCD display works again. I checked the regulator, i found out that there's no short so i tried putting the same diode. Maybe the diode protects it from reverse polarity. I always watching your videos about testing all kinds of module, it helps me to choose what is the best before buying it. :) thank you again sir.

[@tomtouma]

If I have a 24V/10A power supply in to the LM2596, and I'm stepping it down to 12V/420mA for a DC pump, do you think it will still run as hot? I am worried that the LM2596 will always draw 10A as opposed to my pump drawing just what it needs. Thanks Robojax

[@robojax]

The total input power of the module = (output power) + (losses as heat in the module). If you want to get 12V and 0.42A, then the total (input) power is= (12x0.42) + (losses in the module which is about 15%) = 12x0.42 + (0.42* 1.15) = 5.52W. From that you can find the input current = P÷V= 5.25÷ 24=0.23A so at input your will need 0.23A and to be safe assume it a little higher 0.3A would be sufficient. So the 10A you have got at input is just CAPABLE to provide 10A. The system will draw the current(A) amount that it only needs.

[@tomtouma]

​@@robojax So in that case it should be safe to run my 24V/10A PSU through it. I was thinking maybe I'd have to buy a lower amperage PSU but this is good to know. Thanks for your help! I enjoy your videos.

[@robojax]

Yes it is safe. You can use 12V battery with 150A to turn on a small 12V 1A bulb. Only 1A will be drawn from the battery.
