LM2596S input 4V-35V Output 1.23V-30V dc-dc Step-down Power Supply Regulator module

Description

The LM2596 2A Buck Step-down Power Converter Module DC 4V~40V to 1.3V~37V utilizes an advanced microcontroller and comes with a built-in voltmeter display.

LM2596 2A Buck Step-down Power Converter Module Combined with its high-precision multi-turn potentiometer allows for the setting of any desired output voltage within its supply range without the use of an external voltage metre. With a DC input supply range of 4V~40V and a configurable output range of 1.3V~37V, the module has a wide operating range.

Steps to calibrate the output voltage:

Step 1: Set the right button so that the “OUT” LED is lit and the voltmeter displays the output voltage value; press and hold the right button for more than 2 seconds, then release; the voltmeter and “OUT” LED flash in synchronization, indicating that you are in the output voltage calibration mode.

Step 2: Press the right button (normal speed) to add a unit to the voltage value; minus a unit, press the left button Because the lowest voltage display is 0.1V because the unit is less than 0.1V, you must continually press 1-5 times to show the voltmeter change 0.1V, how many times the voltmeter change 0.1V by pressing the key, depending on the current display voltage, the higher the voltage, the fewer the number of press. Step 3: Press the right button for more than 2 seconds, release, to exit the output voltage calibration mode. All parameters are set to automatically power down to save.

Steps to calibrate the input voltage:
Step 1: Set the right button so that the “IN” LED lights up and the voltmeter displays the input voltage value; push and hold the right button for more than 2 seconds, then release; the voltmeter and “IN” LED flash in synchronization, indicating that the input voltage calibration mode has been entered.

Steps 2 and 3 should be done in the same order as the output voltage calibration technique.

Features :

• Input reverse polarity protection
• Built-in output short protection function
• The built-in thermal shutdown function
• Press the right key to let the display show the input or output voltage. when the right “OUT” led light, shows output, the left “IN” led show input.
• Power-off memory function, show that road after power voltage values measured for the last time
• Press the touch button for 3 seconds to turn off the LED display, touch the button again to turn on the LED display
• The band terminals, no iron can also be easy to use, and retention wire connection point
