LM2596 DC-DC Buck Converter Step Down Module

This converter board is working well for stepping down the voltage, however it is not working for stepping up as one might look at its functioning. This has LED to show up that it’s working well. Once set up then it is giving constant output to the set value. Set value don’t change by on/off of this module. I have tested it on battery. On 3.7 volt Li-ion battery it seems to refuse to work very hard. However on 12v SLA battery it is working brilliantly and came down to the most common voltage of 5.0v exactly. Now whenever I’m switching it on it’s giving up fixed output of 5.0 volts. I believe this module has great purpose and solutions to everyday life. For example this can avoid the need of a car charger or another costly charger if wired for charging phones or tablets. Working well. Thanks...,

I bought 2 of the step down converters. One of them has its inductor loose. I had to use hot glue to fix the wobbling because I was afraid that it would break. The converter does not heat up too much so that's good. I have not opened the other one yet but after noticing the wiggle in the first one I checked the other one in the package. The second one was not damaged so that's ok. At last one suggestion that I would give is to have a power indicator light.

The media could not be loaded. I saw a review posted by one of the customer who bought this card. ordered this for gas geyser as tired of changing the batteries.Batteries in this geyser are used for spark ignition and solenoid valve operation.If small amount of voltage drops from batteries those valves were not able to open and ignite the gas geyser and hence everytime had to change the batteries.I don't understand why the manufacturer has not given this system or may be because of safety reasons like what if it doesn't shut the solenoid valves of gas. Anyway i took this risk and fixed it and it's working fantastic.This review is just one day old.May be later i will put after some months usage....I was having normal mobile charger which gives output of 5v i just needed it to step down to 3volt for my gas geyser and here it is works good.Lets see how long this modification lasts .It is very delicate and also i suggest vendor to make a box if it is such a tiny item. Had difficulties in soldering the wire for input and output and had fear that after soldering if it doesn't work. Suggesting to make improved arrangement in your further products....Overall it's good product....thanksReview after 1 year it's still working fine

Potentiometer working goodSome of them are faultyBut u can go for itpricing is not too highThe out put varies in some products and shows steady in some otheres

This circuit is very good for lowering the dc voltage. And it works perfectly. Before you buy this remember these things below.1. It is not reverse polarity protected. Wrong connection will blow it up. So be careful.3. You need a power source at least 5V dc. 3V works but outputs only 0.8V and cannot boost further. Tested with a 5V dc power source and it is able to reduce the voltage to 1.3V. default output is 1.25V can't go below it.4. The blue potentiometer screw is responsive, a slight turn can increase or decrease the voltage.5. Has an LED which glows accordingly. Bright for high voltage and dim for low voltage.Note: if you're using a battery of 1.5V then circuit won't work. It may output same voltage which will make buyers believe that circuit is faulty, but actually it is not. To make it work properly you'll need 5V or above.Overall a nice product and can be used to lower the dc voltage.

Quality prduct good packing
