## Overview

This LM2596 DC-DC buck converter module offers a wide input voltage range (3.2-40V) and a finely adjustable output voltage (1.25-35V) with a maximum current of 3A. Engineered for high efficiency up to 92%, it features low ripple output and robust build quality, making it ideal for professional-grade voltage regulation and power management in diverse electronic applications.

## Description

Description:Module nature: non-isolated buck (BUCK)Rectification method: non-synchronous rectificationInput voltage: 3.2V-40VOutput voltage: 1.25V-35VOutput current: 3A (maximum)Conversion efficiency: 92% (maximum)Switching frequency: 65KHzOutput ripple: 30mV (maximum)Load regulation: ±0.5%Voltage adjustment rate: ±2.5%Working temperature: -40 to +85Peripheral size: 43*21*14 (length * width * height) (mm)Features:1.The module uses high-quality LM2596 chip, high efficiency (maximum 92%), low heat generation, and can easily bring 3A (short-term) current. It is recommended to use current within 2A for long-term work, and add a heat sink (above 10W) Output).2.This module uses the original Sanyo filter capacitor with low ESR, which can make the ripple voltage as low as 30mV, which is completely comparable to the linear power supply!3.This module uses machine placement, reflow soldering, and each module undergoes a two-hour aging test before shipment to ensure high reliability.​ Wiring: 1. Soldering, directly solder the power cord to the input (output) port2. Welding pins can be used by inserting pins through lead wires or inserting into holes on the board; or soldering the PCB directly after adding pins.

## Features

- INPUT VOLTAGE RANGE: DC 3.2V to 40V (The input voltage must be 1.5V higher than the output voltage
- OUTPUT VOLTAGE RANGE: DC 1.25V to 35V continuously adjustable voltage, Maximum output current is 3A.
- HIGH EFFICIENCY: Output with high power conversion efficiency up to 92%. Measured 12V input, 5V output current, 1A load regulation rate is less than 1%.
- USE STEPS: Connect the power supply (3-40V), the power indicator light is on, and the module is working normally; adjust the blue potentiometer knob (usually turn clockwise to boost, counterclockwise to turn down) and use a multimeter to monitor the output voltage until it reaches the required voltage.This module can be used to debug a variety of system operating voltage ranges.
- REQUIRES ATTENTION:It is recommended to use the current within 2.5A for long-term work, and add the scattered Hot plate (output above 10W); because it is a step-down module, in order to ensure stable output, please keep a small 1.5V differential pressure
