This LM2596 - based DC - DC step - down module is a real gem! It uses the LM2596 3A Step - Down Voltage Regulator. The LM2596 regulators are monolithic integrated circuits that handle all the key functions for a step - down (buck) switching regulator. It can drive a 3A load with great line and load regulation. You can choose from fixed output voltages of 3.3V, 5V, 12V, or an adjustable version. It's a non - isolated buck module with non - synchronous rectification. The input voltage ranges from 3V to 40V, and the output voltage is from 1.5V to 35V. The maximum output current is 3A. The module size is 53mm x 26mm. The 'IN+' input is positive, 'IN-' is negative, and 'OUT+' output is positive, 'OUT-' is negative. Also, you can get the datasheet.
Using this LM2596 DC - DC step - down module is easy. First, connect the input power. Make sure to connect the 'IN+' to the positive side and 'IN-' to the negative side of your power source. The input voltage should be between 3V and 40V. Then, connect your load to the output. Connect 'OUT+' to the positive side of your load and 'OUT-' to the negative side. The output voltage can be set between 1.5V and 35V, depending on your needs. If you need a fixed voltage, choose the appropriate fixed - output version. When using it, don't exceed the maximum output current of 3A. Overloading may damage the module. Keep the module in a cool and dry place. Avoid exposing it to high humidity or extreme temperatures. To maintain it, just keep it clean and free from dust. You can refer to the datasheet for more detailed information if you have any further questions.
