- The LM2596 Step Down Buck Converter Module is your go-to solution for efficient DC voltage regulation in any electronics project! This versatile series offers three variants to suit your needs: the basic model without display for simple adjustments, the advanced version with LED display for real-time output monitoring, and the 3VR model with triple adjustable outputs for multi-voltage setups.
- Powered by the reliable LM2596 IC, it steps down input voltages from 4-40V to a stable 1.25-37V output at up to 3A – perfect for powering Arduino boards, ESP32 modules, LED strips, motors, or charging batteries. The built-in potentiometer allows precise tuning, while the high-Q inductor and capacitors ensure minimal ripple for clean power delivery.
- Choose the without-display variant for compact, cost-effective builds; the display model shows exact voltage on a dual-digit LED for easy troubleshooting; or the 3VR for simultaneous 3.3V/5V/12V outputs in one module. All include screw terminals for hassle-free connections and an aluminum heatsink to handle heat during high loads.
- Whether you’re prototyping solar chargers, building RC drones, or stabilizing power in IoT devices, the LM2596 delivers professional performance at an affordable price. Backed by overheat and short-circuit protection, it’s safe and reliable. Order your preferred variant from Dunia BD today and power up your innovations!

FAQ
- What is the maximum input/output voltage for LM2596?
Input: 4-40V DC; Output: Adjustable 1.25-37V DC (do not exceed input by more than 3V). - Does the without-display model need a multimeter for adjustment?
Yes, use a multimeter to fine-tune the potentiometer for accurate output. - How accurate is the voltage display on the with-display variant?
±0.1V accuracy; it shows real-time output voltage for precise monitoring. - What is the 3VR variant used for?
It provides three independent adjustable outputs (e.g., 3.3V, 5V, 12V) from one input – great for multi-rail projects. - Can it handle 3A continuously?
Recommended max 2A for long-term use; 3A for short bursts with good ventilation. - Is it suitable for solar panel applications?
Yes, ideal for MPPT-like step-down in solar charging circuits (4-40V input). - Does it have reverse polarity protection?
No built-in; use a diode on input if needed to prevent damage. - What’s the efficiency compared to linear regulators?
Up to 92% – much better than linear (e.g., 7805 at 40%), saving power and heat. - Can I use it with Arduino?
Absolutely – step down 12V to 5V/3.3V safely without damaging the board. - Warranty and what’s included?
No warranty because all are came from china and we are seller
