§ 02 — Description
The LM2596 converter is designed to step down a DC voltage in the range of 4-35 V to an adjustable output voltage of 1.23-30 V. The module delivers high efficiency (up to 92%), low output ripple (down to 30 mV) and stable output parameters. Thanks to its compact size and easy adjustment (via a trim resistor), it is widely used in electronics projects, laboratory power supplies and standalone systems.
Features
Adjustable output voltage (via potentiometer).
High conversion efficiency (up to 92%).
Low output voltage ripple (30 mV).
Protection against overload and overheating.
Compact size and simple installation.
No additional components required for operation.
Applications:
Power supplies for microcontrollers (Arduino, ESP).
Powering LED strips and low-voltage devices.
Battery charging devices.
Laboratory power supplies (DIY).
Automotive electronics (12 V → 5 V/3.3 V).
DIY projects and amateur radio designs.
Important notes:
The output voltage must not exceed the input voltage.
At currents above 2 A, using a heatsink is recommended.
For precise voltage adjustment, use a multimeter.
Avoid overloads above 3 A to prevent overheating.
