LM2596 DC to DC Buck Converter Module

Product Description :

The LM2596 DC-DC Buck Converter is a high-efficiency step-down voltage regulator module designed to convert higher DC input voltages into stable lower DC outputs. With a wide input range of 3V–40V and adjustable output between 1.5V–35V, it provides up to 3A of output current, making it ideal for DIY electronics, robotics, Arduino, Raspberry Pi, and other embedded projects.

Features:

• Wide input voltage range: DC 3V–40V

• Adjustable output voltage: DC 1.5V–35V

• Max output current: 3A

• Conversion efficiency: up to 92%

• Thickened PCB with Sanyo solid-state capacitors for durability

• High-Q inductor for stable performance

• Built-in short circuit and over-temperature protection

• LED indicator for output status

• Compact size: 45 × 20 × 14 mm

Specifications:

• Model: LM2596

• Switching Frequency: 65kHz

• Rectification: Non-synchronous

• Module Property: Non-isolated buck converter

• Operating Temperature: -45℃ to +85℃

• Load Regulation: ±0.5%

• Voltage Regulation: ±2.5%

Usage Notes:

1. Input voltage must be at least 1.5V higher than the output (no boost).

2. Do not reverse input and output connections.

3. For continuous high current (>2.5A), use a heat sink for stable operation.

Applications:

• DIY power supplies

• Robotics and automation projects

• Arduino & Raspberry Pi projects

• Battery charging modules

• LED drivers and embedded systems

The LM2596 step-down converter is a cost-effective and reliable solution for powering your low-voltage electronics from a higher DC source.
