- Page 5 LM2596S Introduction The AZ-Delivery LM2596S step-down module is a so-called buck converter or step-down converter. This DC-DC converter allows to regulate the input voltage down to a desired value by means of a trimpot. The output voltage is always lower than the input voltage.
- Page 6 LM2596S Specifications Inputs and outputs Screw terminals, solder joints Input Voltage 4 to 40V Output Voltage 3,3 to 24V (adjustable) Output current Max. 3A (enhance cooling at 2A) Adjustment resolution 0,1V Voltmeter accuracy ±(1% +2 Digits) The module has a 3-digit voltmeter display, with the S1 button you can switch between the IN and OUT display: If the LED is on IN, the input voltage is displayed.
- Page 7 LM2596S Measurement error correction function The voltmeter has a measurement error correction function. To enter the calibration mode press the button for more than 4 seconds and release. Now the IN LED lights up and the digital display flashes. With short presses of the switch you can now select a correction value for the input, the value range is -0.5V to 0.5V.
- Page 8 In our example we will power our microcontroller type 1 from AZ-Delivery, for this we use a 12V power supply with the LM2596S to step the voltage down to But before we connect the microcontroller to the step down converter, we first set the correct output voltage.
