LM2596S DC-DC Buck Converter Step Down Buck Converter Voltage Regulator Adjustable Power Supply Module 36V 24V 12V to 5V 2A 4pcs

General descriptionThe LM2596S DC-DC Buck Converter is an adjustable voltage regulator module designed to efficiently step down voltages from 36V, 24V, or 12V to a stable 5V output. It is capable of delivering up to 2A of current, with a maximum output current of 3A, making it suitable for various applications requiring reliable power supply.Technical specificationsInput voltage range: 4V to 40VOutput voltage: Adjustable, with a minimum of 1.25VOutput current: 2A (max 3A)Efficiency: Up to 92%Internal oscillation frequency: 150KHzInstallationA heatsink is recommended for continuous operation above 2A/15W.UsageTo turn off the voltmeter, press and hold the switch for more than 1 second and less than 4 seconds, then release it.Press the switch to turn the voltmeter back on.The indicator light shows the IN/OUT voltage being measured.When first using the module, turn the potentiometer counterclockwise more than 10 times to adjust the output voltage.Other informationThe input and output terminals must not be reversed; the input voltage must always be greater than the output voltage.The module includes protection features against reverse connection, overheating, and short circuits.
