Special Features

  • Practical DC-DC Step-Down Converter The LM-2596 voltage regulator module is suitable for step-down conversion applications where the input voltage exceeds the output voltage. Connect the power supply to the positive and negative terminals of the adjustable step-down module's input, and connect the output device to the positive and negative terminals of the step-down module's output. Supporting a wide input voltage range from 3.2V to 35V, it is ideal for various applications including DIY electronics and solar power systems. (Input voltage must be at least 1.5V higher than output voltage).
  • Convenient Operation for Peace of Mind Connect the power adapter to the input terminals of the LM-2596 DC-DC buck converter. Use a multimeter to check the output voltage value. If the output voltage does not match your electrical device, use a mini screwdriver to adjust the screw on the blue potentiometer. (Turn clockwise to increase voltage; turn counterclockwise to decrease voltage.) Once the output voltage value matches, connect to the output device.
  • High-Efficiency Output: This buck regulator achieves up to 92% conversion efficiency, ensuring stable and efficient voltage regulation for your devices from 1.25V to 34V. Output ripple is less than 30mV, with a switching frequency of 65KHz and an operating temperature range of -45°C to 85°C.
  • Operating current reaches approximately 2A (maximum 3A). Allow sufficient thermal headroom. For loads exceeding 10W, add heat dissipation measures to ensure safe system operation. Verify polarity with a multimeter during initial power-up to protect sensitive loads.
  • Featuring the second-generation LM-2596S chip paired with a 100 µH large inductor for stable current delivery, this converter is highly suitable for DIY projects or industrial equipment applications. Whether you're a professional or a beginner, this converter is your ideal choice.

Description

When powering on the LM-2596S adjustable buck boost converter for the first time, verify polarity using a multimeter to protect sensitive loads.
Precautions
1. Voltage Limitations
Input voltage range: 3.2~35V (must be ≥ output +1V)
Output voltage range: 1.25~34V
Factory default is set to 18V high voltage. Rotate the blue potentiometer screw counterclockwise approximately 10-15 turns before output voltage changes.
2. Heat Dissipation Requirements
Heat sinks must be added when load > 10W or current > 2A to prevent overheating damage.
A 0.1μF high-frequency bypass capacitor at the input effectively filters high-frequency noise.
