## Overview

The 4Pack LM2596 DC-DC Buck Converter is a high-efficiency voltage regulator that allows you to step down voltage from 3-40V to a customizable output of 1.5-35V. Ideal for various electronic projects, this pack of four modules ensures you have the power you need, when you need it. With a maximum output current of 3A (with heatsink), these converters are perfect for both hobbyists and professionals alike.

## Description

Features:The input voltage: 3-40 VThe output voltage:1.5-35 VThe output current: It is recommended to use under 2A, maximum 3A (Additional heatsink is required).Conversion efficiency: 92% Max (the higher output voltage, the higher efficiency)Load adjust ratio: +/-0.5%Voltage adjust ratio: +/-2.5%Switching frequency:1.5MKHzWork temperature:-Minus 40 degrees-85 degreesModule property:Non-isolation buckRectification mode:Non-synchronous rectifierFunction:1.Used to step down load, built in current limit function2.Built in over-temperature protection function3.Built in output short-circuit protection functionPackage includes:4X LM2596 step down module❥(^_-).Share your project below:Share your problem-solving process or video to help other friends solve problemsAbout us： Professional factory, welcome to our store for more choices with best price.

## Features

- The input voltage: DC 3 -40 V (Input voltage must be 1.5 V higher than the output voltage, no boost.)
- The output voltage: DC 1.5 - 35 V adjustable.
- The output current: It is recommended to use under 2A, maximum 3A(Additional heatsink is required).
- Steps: 1. Plugged into a power supply (3-40v), the power indicator light is lit, the module to work properly. 2. Adjust the blue potentiometer knob (generally booster clockwise, counterclockwise step-down) with a multimeter monitoring the output voltage to the voltage.
- Package includes:4XLM2596 DC-DC buck converter module（Note：The factory have tested these at max voltage so they are very high by default, takes about 15-20 turns CCW before the voltage starts ramping down)
