LM2596HVS DC-DC Buck Converter Module 4.5-53V to 3-40V 3A Step-Down

🔧 LM2596HVS DC-DC Step-Down Module | AuscomTech

The LM2596HVS is an adjustable DC-DC step-down module designed to convert a higher DC input voltage to a lower regulated output voltage.

It provides efficient voltage conversion for powering embedded electronics, controllers, development boards, sensors, and other low-voltage DC devices from a higher-voltage source.

This module is suitable for DIY electronics, Arduino and ESP32 projects, battery-powered systems, automotive applications, and general-purpose DC power regulation.

⭐ Key Features

• Wide Input Range – Accepts DC input from 4.5V to 53V.
• Adjustable Output – Output voltage can be regulated from 3V to 40V using the onboard trimmer potentiometer.
• Up to 3A Output – Suitable for a wide range of low-power to moderate-power DC loads.
• High Conversion Efficiency – Efficiency rated up to 92% under suitable operating conditions.
• Low Output Ripple – Output ripple specified at less than 30mV.
• Compact Module – Small PCB footprint makes it easy to integrate into enclosures and custom builds.
• Clearly Marked Connections – Input and output polarity are labelled on the board for easier wiring.

⚠️ Important Notes

• Step-down converter only – input voltage must be higher than the required output voltage.
• Output voltage is adjustable; turn the potentiometer counterclockwise to decrease the voltage.
• Some modules may ship with the default output set around 20V.
• If the output initially appears not to adjust, rotate the potentiometer counterclockwise for more than 10 turns and test again.
• A heatsink is recommended when power exceeds 15W to improve heat dissipation.
• Please confirm polarity before connecting power or load.
