LM2596 2v-37V 3A Voltage Step Down converter Module Tested/Reviewed

I ordered a bunch of these, when they first came out I paid less than $1.00 USD each, but I purchased a bunch of them. I never used them because bigger and better ones came out. These work best if your input is very close to your output. Hooked up to the car battery 13.8v and I need 12v @ 1.5amp I stand a good chance, even 2.0amp maybe with a small heatsink from a Raspberry PI

can i use it when the input of the module is 12V 10A ?

Can we adjust the output current (amp)??

input Amp and output Ampere always same, only voltage change on theses typ converter. You don't show input Amp?

good tests , thanks

Thankyou very much sir, that was very interesting.

Brother, please, does the circuit heat up when loading anything
When I turn on a router of no more than 1 Amp, I find that IACI overheats with
Diode and transformers, and with an output capacitor, what causes the problem?
Is it natural in itself
answer please
With problem solving
thank you very much

is it ok to input 60v by changing input capacitor voltage to 100v?

can I use the 5v output voltage from the converter to safely charge my phone?

You can read in the specs, that you need to add a heat sink if the output power is greater than 15W.

I made an ultrasonic sensor project with Arduino Uno and I have powered 5v 3a from the step down module connected to the 12v 3a adapter. what happens is that my ultrasonic sensor is always on, normally the sensor will on if the triger is on. what's the problem?

HELP! My OUT LED is red, and the potentiometer is doing nothing!

First, there is a 48uH Inductor, the datasheet say 33uH. 2. the input cap is only 100uF, in the datasheet is 680uF. 3. there is no heatsink on the board, only a very litle copper on the tab. And last the quality of the inductor is not great. Over all 2A are fine.

If you can't touch it for more than a few seconds then it's over 70 degrees C, i've read. I'm using these in a project and they seem fine but i never go over 700mA. Thanks again for your very useful reviews 🙂

i have rather bad experience, first they getting hot, 12V input 5V output 1A .. lifetime is about 3-5 month until they start heating extremely up and die
i used arround 40 units in projects .. they are all replaced now with xl4015 based converters which stay much cooler, lets see how there lifespan is.
btw, RFI is much lower as well, of corse depends on the implementation …but….

How much ampere input can handle this module sir? Can be handle 15amp?

I saw video using this module with gsm module. I want to do the same but not sure what input and output should be. please help.

Can i use this as a charger for phone? My phone required 5volt 2A,

Sorry, but I think this a STUPID REVIEW !
This is a voltage Regulator – emphasis on VOLTAGE, and it can handle a maximum of 3 Amp. Thats the "peak Amp" for a short time, as per manufacturer, so why do you want to challenge that? 3 Amps peak, and 2 Amps max for long duration … that is clear.
However, it would have been more interesting to see so how stable the output-voltage remains if the input-voltage changes = REGULATE VOLTAGE (not Amps).
For example if I use it in my car, the normal car-battery voltage is 12.3V and if it stands for a long time it might go down to 11.8V and if I start the motor it might even dip more, but if the alternator is charging it can go upto 14.4V >>> can this LM2596-thingy give me a constant 5.00 Volts ???

Let's say we use it for 24 volt battery and we need 13 volt on out put is it gonna drop the the voltage as the battery is dropping voltage or it stays at 13 volt while battery voltage is coming to 13 volt ?
Plz

Nice video , is the output completely isolated from the input?

This says 0-5amps and up to 75 watts https://www.amazon.com/Adjustable-Converter-1-25-36v-Efficiency-Regulator/dp/B079N9BFZC/
Is this true or are they lying? Would it do 19v -> 12v with 3.5A output if you used a heatsink?

Mine always blow up with 9v input and 3.3v output 🙁

Does it work on unregulated DC supply coes from solar panel ?

I cannot thank you enough for making such an informative video on ymthis module

thanks

Great video. Very informative !. I would like to know about your test load. That looks fancy !

Thank you for a great video!

thank you! I thought mine was damaged!! I turned a lot with no result. I was about to bin it!

This is my goto material on the use of this module, your thorough testing in different ranges makes this video reference gold. I've come back to watch it again each time I use one of these just to be sure of it's performance in my targetted load case, brilliant sir.

good explained ,thank You
Still a question ,can you put on the out a battery it would be fantastic speciale when it comes from sunpower,thank You
