LM2596 DC-DC Step Down Module with Fixed 3.3 V Output

Information about this module is generated with the help of AI. The description may be incomplete, inaccurate, or subject to change.
The LM2596 DC-DC Step Down module with fixed 3.3 V output is designed to convert a higher DC input voltage into a stable 3.3 V output with high efficiency. It is based on the well known LM2596 switching voltage regulator and is suitable for powering microcontrollers, sensors, communication modules and other electronic devices requiring a stable 3.3 V supply.

Unlike a linear voltage regulator, the LM2596 uses switching technology, resulting in significantly lower heat generation and higher efficiency. The conversion efficiency can reach up to 92 percent depending on input voltage, load and cooling.

The fixed 3.3 V version requires no output adjustment, making it simple to use in both prototypes and finished products.

See the attached experiment for instructions on how to disable the module.

The 150 kHz switching frequency allows the use of relatively small external components while maintaining a stable output voltage with low ripple.

The module is ideal for Arduino, ESP32, ESP8266, Raspberry Pi, development boards, industrial control systems and many other applications requiring a reliable 3.3 V power supply.
