As with most of the devices here we also have to provide sufficient cooling for it to work long and reliably. This steps shown here are from now on implied on all of the examples.Ĭurrent rating of the IC LM2596 is 3 Amps (steady current), but if you actually pull through it 2 or more Amps for a long period of time it will heat up and burn out. In the next couple of steps we would like to show you couple of examples on how to produce certain voltages and when to use these voltages. Now that the voltage is appropriately adjusted, instead of the multimeter connect the device/module you want to power.Sometimes when you use the converter for the first time you will have to rotate the trimmer screw 5-10 full circles to get it working. Feel free to turn the trimmer in both directions to get the feeling how to work with it. Adjust the trimmer (here 20k Ohm) with a tiny screwdriver until the voltage is set to the desired output. Now you can already see the voltage on the output.
