LM2596S DC-DC Power Supply Adapter Step Down Module
The LM2596S is a highly efficient DC-DC step-down voltage regulator designed to convert a higher input voltage into a stable, lower output voltage. It is ideal for powering low-voltage electronics from a higher-voltage power source, offering a flexible and reliable solution for a variety of applications.
This module supports an input voltage range from 3V to 40V and provides an adjustable output voltage from 1.25V to 37V, with typical efficiency exceeding 90%. It includes the LM2596S IC, an inductor, diode, and other passive components, and some versions are equipped with LED indicators to show the status of the input or output voltage.
The module’s built-in safety features include short-circuit protection and thermal protection to prevent overheating, ensuring safe and stable operation even under heavy loads.
Key Features:
- Efficient Voltage Conversion: Utilizes the LM2596S integrated circuit, a switching regulator that ensures high efficiency during voltage conversion.
- Wide Input Voltage Range: Supports input voltages from 3V to 40V, providing flexibility for a wide range of applications.
- Adjustable Output Voltage: Output voltage can be adjusted from 1.25V to 37V, with typical efficiency greater than 90%, making it perfect for powering various devices.
- Compact Design: The module is compact, making it suitable for use in tight spaces in electronics projects.
- LED Indicators: Some versions feature LED indicators to show the status of input and output voltages.
Applications:
The LM2596S step-down voltage regulator is perfect for a variety of applications:
- Powering Microcontrollers: Ideal for powering microcontroller-based projects with different voltage requirements.
- Supplying Low-Voltage Devices: Use the LM2596S to step down voltage from higher sources to supply power to lower voltage devices (e.g., powering a 5V or 3.3V circuit from a 12V power supply).
- DIY Electronics Projects: Perfect for hobbyists and makers who need a reliable and adjustable power source for custom electronics projects.
For example, you can use it to step down a 9V battery to power a 3.3V controller with less than 8% energy loss, making it both efficient and practical.
