Beier LM2596S DC/DC Converter

Beier LM2596S DC/DC Converter

Description
The LM2596S DC/DC converter is a small module that converts a higher input voltage into a lower output voltage. This is a stepdown switching regulator with a high efficiency (up to 90%) and little loss (heat).

The input voltage can be in the range of 4 - 37 V. The output voltage can be adjusted between 1.25 - 35 V using a spindle trimmer. However, the voltage at the input (IN) must always be at least 2.0 V higher than the output voltage (OUT).

The module has 4 solder terminals for the input and output voltage:
IN+:
IN-: Â Â Input voltage plus
Input voltage minus/GND
OUT+:
OUT-: Â Â Output voltage plus
Output voltage minus/GND

The LM2596S DC/DC converter has a common ground (GND) at the input and output. The voltages are therefore not galvanically isolated.

The output voltage is set to 5.0 V as delivered.

Application examples:
Supply of a sound module if only a higher battery voltage (eg 24 V) is available in the model
Generation of a BEC voltage from the main battery
Power supply for microcontrollers (Arduino, Raspberry Pi, ESP32, etc.)
DIY/self-build electronics projects
