LM2596S DC-DC Step-Down Power Supply

LM2596S DC-DC Step-Down Power Supply

The LM2596S DC-DC Buck Converter is a highly efficient, step-down switching regulator designed to deliver stable power for various applications. It supports both fixed output voltages (3.3V, 5V, 12V) and an adjustable output version, providing flexibility for diverse projects. With a rated output current of 2A and a maximum capacity of 3A (with a heatsink), this module is ideal for powering microcontrollers, sensors, and other electronic devices.

Operating at a high switching frequency of 150kHz, the LM2596S minimizes the size of required filter components compared to lower-frequency switching regulators. It features excellent line and load regulation, making it a reliable choice for stable voltage outputs.

This module is equipped with a high-precision potentiometer for easy adjustment of the output voltage, and its efficient switch-mode design outperforms traditional linear regulators, especially at higher input voltages.

Features:

• Wide Input Voltage Range: Supports 3V to 40V input voltage.
• Adjustable Output Voltage: Provides an output range of 1.5V to 35V.
• High Current Capability: Rated for 2A output, with a maximum of 3A (requires an additional heatsink for continuous operation).
• High Efficiency: Conversion efficiency up to 92%, depending on load and input/output conditions.
• Switching Frequency: Operates at 150kHz for reduced filter component size.
• Compact Design: Includes an SMD LED for operational indication.
• Integrated Protection: Current limiting for short circuit protection with automatic recovery.
• Ease of Use: Simplifies power supply design with internal compensation and minimal external components.

Applications:

• Microcontroller and sensor power supply (e.g., Arduino, Raspberry Pi).
• Power regulation for portable devices.
• DIY electronics projects requiring stable voltage conversion.
• Battery-operated devices.
• Adjustable voltage power supplies.

The LM2596S DC-DC Step-Down Module provides a versatile and efficient solution for powering your electronics, combining compact design, high efficiency, and excellent reliability.
