Adjustable LM2596/LM2596S DC-DC step-down converter module with SMD LED indicator

Adjustable Step-Down DC-DC Converter (Buck Converter) 3.2V–35V / 1.25V–30V 3A. Are you looking for a reliable and efficient solution for voltage regulation in your electronic projects? This compact step-down (Buck) converter allows you to easily reduce the input voltage to the required level with high efficiency of up to 92 per cent. It is ideal for powering DIY projects, LED strips, microcontrollers (Arduino, Raspberry Pi), educational modules or car accessories.. Key benefits and features. - Wide voltage range: It handles input voltages ranging from 3.2 V to 35 V and allows for smooth output adjustment from 1.25 V to 30 V.. - High efficiency: Thanks to a switching frequency of 65 kHz, it achieves a conversion efficiency of up to 92 per cent, ensuring minimal energy loss and less unnecessary heat generation.. - Current output up to 3 A: The module can supply an output current of up to 3 A, which is sufficient for most common electronic applications.. - Visual indication: An integrated red LED indicator immediately informs you of the power supply status.. - Compact design: The small dimensions of the PCB allow for easy installation even in space-constrained enclosures and devices.. Technical specifications:. - Converter type: Step-down (Buck). - Input voltage: DC 3.2 V – 35 V. - Output voltage: DC 1.25 V – 30 V (adjustable). - Output current: Max. 3 A. - Conversion efficiency: Max. 92%. - Switching frequency: 65 kHz. - Power indicator: Red LED. Important operating instructions:. - Observe polarity: Before connecting, carefully check the positive (+) and negative (-) terminals at both the input and output.. - Reversing the polarity will cause permanent damage to the module.. - Step-down (Buck) converter: This is exclusively a step-down converter – the input voltage must always be higher than the required output voltage.. - Cooling under heavy load: If the module is operated for extended periods, or if the output current exceeds 2.5 A or the power output exceeds 10 W, adequate cooling must be ensured (e.g. using an additional heat sink).. - Efficiency: Actual efficiency depends on the difference between the stage-to-stage voltage and the current drawn.. Packaging: 1 piece. The product is not a self-contained unit and requires professional installation.
