## Overview

The Songhe LM2596S Buck Converter is a high-efficiency DC-DC voltage regulator that allows you to step down voltages from 3.2V to 35V to a desired output between 1.25V and 30V. With a maximum output current of 3A and an efficiency of up to 92%, this module is perfect for powering various devices like phones and gaming consoles. Its compact design and adjustable settings make it an essential tool for any DIY electronics project.

## Description

Electrical parameters: Input: DC 3.2V to 35V (input voltage must be more than the output voltage can not be higher than boost 1.25v.) Output: 1.25V to 30V DC voltage is continuously adjustable, high efficiency and maximum output current of 3A. Features: All solid capacitors using SANYO, 36u thick circuit boards, high-Q inductors with high power output LED indicator Size: 41 (L) * 20 (W) * 14 (H) mm (including potentiometers) Taobao minimum with locating hole with LED indicator DC-DC Instructions: Access to power (3-35V), adjust the blue potentiometer knob (clockwise rotation generally boost, buck counterclockwise rotation) and with a multimeter to monitor the output voltage reaches the required voltage. Wiring: 1. welding, welded directly to the power line input (output) port; 2. solder pins, or pins can be inserted through the lead insertion use in tunnel plate; soldered directly to the PCB after another or add pins.

## Features

- Input voltage range: DC 3.2V to 35V (input voltage must be higher than the voltage output to 1.5V or more can not be boosted.)
- Output Voltage Range: 1.25V to 30V DC voltage is continuously adjustable, high efficiency (maximum 92%) of the maximum output current of 3A.
- Found 12V input, load regulation 5V 1A output current is lower than 1%;Note: The input and output can not be reversed, reverse might burn chips;
- This is a step-down module, the input voltage is higher than the required output voltage;
- Output 2A or less long period of time without additional heat sink output current is greater than 2.5A (or output power greater than 10W) to work long hours please add heat sink.
- The vehicle power supply, only need to enter this module termination point the car cigarette power supply, you can adjust the potentiometer, the output voltage can be adjusted in 1.25-30V, for your phone, MP3, MP4, PSP charging many devices powered, very simple and convenient.
- The power to the electronic device when the device needs 3-30V power supply voltage corresponding to the hand while using this module you can easily put the voltage to the desired voltage and solve problems.
- The system voltage test can be used to make this project a variety of debugging module voltage test system operating voltage range, very easy and convenient.

    One of them was broken in the bag
  

*by S***T on Reviewed in the United States on January 28, 2023*

I bought these to add LED lighting to my 3D printer.  The printer supplies 24v, LEDs require 5v, so buck converter to the rescue.  The converter works great, although the first one I used came out of the bag broken.  It had to arrive that way because I separated the module outside the bag, but the broken part was at the bottom of the bag.  For what they do, these are really inexpensive and easy to use if you are okay soldering.  If you aren't, don't worry, the solder pads are plenty big and isolated from any heat sensitive components.  I had no problem getting the voltage set to 5.06v.  You can't get it exact, but that is plenty close to what I needed.If one didn't arrive broken, I would have given this 5 stars.

Nice little buck converter fro Arduino projects.. Be sure to connect your input voltage source and then adjust for the output voltage before connecting your Arduino or other chosen component.
