What it does
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
Good to know
- 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
