LM2596 CC CV Step Down Buck Converter Module 3A

The LM2596 Constant Current (CC) and Constant Voltage (CV) Step-Down Buck Converter Module is a highly efficient DC-to-DC power regulator designed for precision voltage and current control. Built around the reliable LM2596S-ADJ regulator IC, this module allows you to step down input voltages ranging from 7V to 35V to a highly stable, adjustable output of 1.25V to 30V. With its dedicated constant current adjustment potentiometer, it serves as an excellent current-limiting power source, preventing damage to sensitive downstream electronics.

This versatile module is widely used as a high-efficiency LED driver, a solar panel battery charging regulator, and a dedicated lithium-ion/LiFePO4 battery charger. It features three onboard multi-turn precision potentiometers to adjust the output voltage, output current limit, and charging indicator threshold. Integrated LED indicators provide real-time status updates, showing whether the module is in constant current mode, actively charging, or fully charged, making it a staple for DIY lab power supplies and smart robotic systems.

Features:

• Dual CC/CV Control: Fully adjustable output voltage and current limits for precise power delivery.
• High Conversion Efficiency: Delivers up to 92% efficiency, minimizing heat dissipation during operation.
• Onboard LED Indicators: Dedicated LEDs for OK (Fully Charged), CH (Charging), and CC/CV (Constant Current/Voltage) status.
• Wide Input Range: Accepts input voltages from 7V to 35V DC, compatible with standard adapters and batteries.
• Low Ripple Performance: High-frequency filter capacitors ensure clean, low-noise output voltage.
• Robust Protection: Features built-in thermal shutdown and short-circuit protection for safe operation.
