Product Overview

The DC-DC Buck Converter Module is a high-efficiency step-down power supply designed to convert higher DC input voltages (such as 12V) into stable lower outputs like 3.3V, 5V, or 12V. Built using the reliable LM2596 switching regulator, this module is ideal for powering microcontrollers, sensors, and embedded systems in STEM and DIY electronics projects.

Key Features

Supports multiple output voltages: 3.3V, 5V, and 12V (based on variant)
High efficiency up to approximately 90%
Wide input voltage range
Capable of delivering up to 3A output current
Stable output with good line and load regulation
Compact and easy-to-integrate design
Built-in thermal shutdown and current limiting protection

Technical Specifications

Input Voltage: 4V to 40V DC
Output Voltage: 3.3V / 5V / 12V (fixed or adjustable variants available)
Output Current: Up to 3A
Switching Frequency: 150 kHz

Disclaimer

Output voltage may require manual adjustment (for adjustable variants) using the onboard potentiometer.
Ensure the input voltage is always higher than the desired output voltage.
Heat dissipation may be required for high current applications.
Not suitable for precision analog circuits without additional filtering.
Actual performance may vary based on load conditions, input voltage, and environmental factors.
