Description

High-Efficiency LM2596 Buck Adjustable Step Down DC-DC Converter

Technical Specifications of LM2596 Power Supply Module

• Input Voltage Range: Accepts DC inputs from 4.5V up to 40V.

• Output Voltage: Adjustable from 1.25V to 35V via multi-turn potentiometer.

• Current Capacity: Rated for 2A continuous output and 3A with cooling.

• Switching Frequency: High-speed 150kHz internal oscillation for low ripple.

• Conversion Efficiency: Achieves up to 92% efficiency under typical load conditions.

• Regulation: Excellent line and load regulation with ±0.5% stability.

• Operating Temperature: Industrial grade performance from -40°C to +85°C.

• Protection: Integrated thermal shutdown and current limit safety features.

Usage and Voltage Calibration

• First, connect your unregulated DC source to the IN+ and IN- pins.

• Next, observe the input voltage to ensure it exceeds the target output.

• Then, monitor the output terminals with a precision digital multimeter.

• Afterward, turn the potentiometer screw counter-clockwise to decrease the output voltage.

• Consequently, the LM2596 Power Supply Module delivers a stabilized lower voltage.

• Finally, solder your output wires once the desired voltage level is fixed.

Advantages and Disadvantages of LM2596 Power Supply Module

• Pros: Compact size allows for easy integration into portable electronic projects.

• Furthermore, the switching design generates far less heat than linear regulators.

• Cons: The output voltage must be at least 1.5V lower than the input.

• Additionally, drawing 3A for extended periods requires an external aluminum heatsink.

Precautions and Installation Safety

• Warning: Avoid reversing the input polarity as it will destroy the IC.

• Never exceed the 40V input limit to prevent capacitor failure.

• Ensure adequate airflow when operating at high current levels.

What is Included in the Package

• 1x LM2596 Power Supply Module with pre-installed potentiometer.

• High-quality electrolytic capacitors for low-noise output performance.
