LM2596 Buck Converter Module DC-DC Step Down Power Supply

The LM2596 Buck Converter Module DC-DC Step Down Power Supply is a high-efficiency step-down voltage regulator. It efficiently converts higher DC voltages to lower voltages, making it essential for powering 5V devices from 12V batteries or other high-voltage sources.

Key Features

• High efficiency up to 96% (depending on input/output)
• Adjustable output from 1.25V to 35V
• Input voltage range 3.2V to 40V
• 3A max output current with heatsink
• Built-in current limiting and thermal shutdown
• Low ripple and noise output
• Compact size with LED indicator

Technical Specifications

Applications

• 12V to 5V conversion for Arduino/Raspberry Pi
• Battery-powered projects
• USB power supply from higher voltage batteries
• LED driver applications
• Vehicle electronics (12V/24V to 5V)
• Solar panel voltage regulation

Important Notes

• Adjust output voltage with potentiometer BEFORE connecting load
• Heatsink required for currents above 2A
• Input voltage must be at least 1.5V higher than output voltage
• Ripple increases at higher load currents – add output capacitor if needed
• Do not exceed 3A output – converter will overheat
• Verify output voltage with multimeter after adjustment
