hiBCTR 10 Packs LM2596 Buck Converter DC to DC Step Down Voltage Regulator, 3.0-40V to 1.5-35V Adjustable Power Supply Module, High Efficiency

HIGH PRECISION VOLTAGE REGULATION: Equipped with a high-precision multi-turn potentiometer, this LM2596 buck converter allows you to finely adjust output voltage from 1.5V to 35V. Note: For the initial setup, you may need to turn the screw counter-clockwise multiple times before the voltage starts to change. WIDE INPUT RANGE SPECIFICATIONS: Supports a broad input voltage range of DC 3.0V to 40V. This step-down module ensures stable operation provided the input voltage is at least 1.5V higher than the desired output voltage (Buck mode only, does not boost voltage). ROBUST & EFFICIENT BUILD: Engineered for reliability with SANYO solid capacitors, 36u thick circuit boards, and high-Q inductors. This rigorous construction enables up to 92% conversion efficiency and includes an LED indicator for instant working status monitoring. VERSATILE DIY APPLICATIONS: An ideal power solution for various electronics projects. Perfectly suited for DIY mobile power banks, powering monitors, communication devices, solar panels, and regulating voltage for custom electronic equipment integration. COMPACT STEP-DOWN MODULE: Featuring a space-saving design without compromising performance. The dense PCB layout allows for easy integration into small enclosures or control boxes, providing a steady power supply for space-constrained engineering tasks.
Product Description



Unlock Precise Power Control with hiBCTR LM2596 DC-DC Buck Converter



The hiBCTR LM2596 Step-Down Module is a high-performance voltage regulator designed for electronics enthusiasts and engineers. Whether you are building a custom power bank or regulating voltage for sensitive communication equipment, this module delivers stability and efficiency.



Technical Specifications:



Model: LM2596 DC-DC Buck Converter



Input Voltage: DC 3.0V - 40V



Output Voltage: DC 1.5V - 35V (Adjustable)



Conversion Efficiency: Up to 92% (Max)



Switching Frequency: 150KHz



Operating Temperature: -40°C to +85°C



Key Components: SANYO solid capacitors, 36u thick PCB, High-Q Inductor



How to Adjust Voltage:



Connect the power source to the input terminals (ensure correct polarity: IN+ to Positive, IN- to Negative).



Use a multimeter to monitor the output voltage at the output terminals.



Use a small flathead screwdriver to turn the brass potentiometer screw on the blue component.



Important: Turn Counter-Clockwise to decrease voltage and Clockwise to increase. You may need to turn it 10-20 full rotations before the voltage changes significantly.



Usage Scenarios:



DIY Electronics: Perfect for breadboard power supplies and Arduino/Raspberry Pi projects (with proper voltage setting).



Solar Power: Regulate fluctuating voltage from small solar panels.



Device Power Supply: Ideal for powering monitors, LED displays, and other DC appliances requiring specific voltages.



Note: This is a step-down module (Buck); the input voltage must be higher than the output voltage (minimum 1.5V difference). It cannot boost voltage.
