DC-DC Buck Converter Module (LM2596 / MP1584)
—A DC-DC buck converter steps a higher DC voltage down to a lower one efficiently, letting a 12V or 24V supply run 5V or 3.3V electronics without wasting power as heat.
Specifications
- LM2596 (adjustable, ~3A) or MP1584 (compact, ~3A) variants
- Input typically 4-35V, output adjustable 1.25-30V
- Efficiency commonly 85-92%
- Trimmer potentiometer sets the output voltage
- Some versions include a voltage display
- Set the output before connecting a load
What you can build with the DC-DC Buck Converter Module (LM2596 / MP1584)
- Running 5V electronics from a 12V battery
- Solar and off-grid power stages
- Vehicle and caravan projects
- Powering a Raspberry Pi from a higher-voltage supply
- LED strip supplies at a set voltage
Compatibility
Works with any project needing a regulated DC rail — Arduino, ESP32, Raspberry Pi and Pico. Far more efficient than a linear regulator, which turns the voltage difference into heat. Always set the output voltage with a multimeter before connecting the load.
