DC-DC Buck Converter (LM2596) with Display


This is a DC/DC step-down voltage regulator that converts input voltage between 3.2V and 40V into a smaller voltage between 1.25V and 35V, capable of driving a 3A load with excellent line and load regulation. 
In some projects, you might need different voltages (3-35V) for your devices. Without this kind of DC power source, you’ll find it time-consuming to buy a new one. The delay of project is so annoying. No worries! This module can accelerate prototyping, because you can get the voltage you need (such as 3.3V, 5V and 9V) as easy as blinking eyes.
  • Input Voltage: 3.2V - 40VDC
  • Output Voltage: 1.25V - 35VDC
  • Max. Output Current: 3A
  • Max. Efficiency: 92%
  • Output Ripple: ≤100mV
  • Switching Frequency: 65KHz

How do i regulate output voltage with this? Is there any potentiometer or something for regulation?

Hello, please see the picture carefully. There is a blue variable resistor on board.

Got it.Thanks.

My exact need is: 5v input 12v output ! So this could give me the solution right?

Never! You do not need buck. You need boost.

Is the onboard switch a momentary power switch for the module?

Input/output selector switch for display.

Is the output voltage dependent on input voltage or it will remain constant no matter the input voltage as long as input is higher than output?
