PRODUCT DESCRIPTION

The 2596A Step-Down DC-DC LM2576 Adjustable Voltage Regulator is an efficient and reliable power module designed for precise voltage regulation. It features high-frequency X7R bypass capacitors at the input and output terminals, ensuring superior electromagnetic compatibility.

Input Voltage Range: DC 3.2V to 35V (with a requirement that the input voltage be at least 1.5V higher than the output voltage; it does not support voltage boosting).

Output Voltage Range: DC 1.25V to 30V, with continuous adjustability. The module delivers high efficiency (up to 92%) and can supply a maximum output current of 3A.

Performance: When tested with a 12V input and 5V output at 1A, the voltage adjustment rate is less than 1%, demonstrating excellent stability and precision.

Note:

The input and output must not be connected in reverse, as doing so can damage the chip.

This is a step-down module, so the input voltage must always be higher than the output voltage.

For outputs below 2A, the module can be used continuously without a heatsink. However, if the output current exceeds 2.5A or the output power surpasses 10W, a heatsink is recommended for extended operation to prevent overheating.

How to Use LM2596S DC-DC 24V 40V to 12V 9V 5V 3V Adjustable DC

Connect the module’s VIN+ and VIN– to your DC source (ensuring input is ≥1.5 V above desired output). Use a multimeter on VOUT terminals while rotating the onboard potentiometer to set the required voltage. After adjustment, hook up your load and, for sustained high current, attach a small heatsink or ensure adequate airflow.

Frequently Asked Questions

What is the recommended input voltage for stable 5V output?

To achieve a stable 5V, provide at least 6.5V input (1.5V above the desired output), within the module’s 3–40V range. Use a regulated DC source to avoid voltage spikes.

How much current can I draw from this module?

The LM2596S board can deliver up to 3A continuously. For loads near the upper limit, attach a heatsink and ensure proper ventilation to maintain reliable operation.

Does this module include short-circuit or thermal protection?

This design uses high-quality Sanyo capacitors and a 36μm PCB for stability, but it does not feature built-in short-circuit or thermal shutdown. We recommend external fuses or current-limiting devices for sensitive applications.
