Utilizing the robust LM2596 switching regulator IC, this imported module is capable of driving a 3A load with excellent line and load regulation.\u003c\/p\u003e\n\n\u003cp\u003eThe output voltage is easily customized using the onboard high-precision multi-turn potentiometer. Because it uses a switching design, it operates with a much higher efficiency (up to 92%) compared to traditional linear regulators like the LM7805, meaning less energy is wasted as heat. It is a mandatory component for battery-powered robotics, custom microcontroller projects, and general low-voltage electronics prototyping.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eAlso searched as:\u003c\/strong\u003e lm2596 buck converter, dc to dc step down module, 3a adjustable voltage regulator, arduino 5v power module, lm2596s dc-dc imported.\u003c\/p\u003e\n\n\u003chr\u003e\n\n\u003ch5\u003eTechnical Specifications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCore IC:\u003c\/strong\u003e LM2596S-ADJ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput Voltage Range:\u003c\/strong\u003e 3.2V to 40V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Voltage Range:\u003c\/strong\u003e 1.25V to 35V DC (Continuously Adjustable)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Current:\u003c\/strong\u003e 2A (Continuous), 3A (Maximum with additional heatsink)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConversion Efficiency:\u003c\/strong\u003e Up to 92% (depending on input\/output voltage differential)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitching Frequency:\u003c\/strong\u003e 150 kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput Ripple:\u003c\/strong\u003e \u0026lt;30mV\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eModule Dimensions:\u003c\/strong\u003e ~43mm × 21mm × 14mm\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eCommon Applications\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMicrocontroller Power:\u003c\/strong\u003e Stepping down a 12V or 24V power supply or battery pack to a clean 5V to safely power Arduino, Raspberry Pi, and sensor arrays.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMobile Robotics:\u003c\/strong\u003e Regulating high-voltage LiPo batteries down to safe operating voltages for logic boards, servo motors, and wireless communication modules.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLED Driving:\u003c\/strong\u003e Providing a stable, adjustable voltage source to power custom LED lighting strips or high-power LEDs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDIY Bench Power Supply:\u003c\/strong\u003e Acting as the core regulation component for a compact, custom-built variable desktop power supply.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch5\u003eFrequently Asked Questions\u003c\/h5\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can this module increase (step-up) the voltage?\u003c\/strong\u003e\u003cbr\u003e\nA: No. This is strictly a step-down (buck) converter. The input voltage must always be at least 1.5V higher than your desired output voltage for the module to regulate properly.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to attach a heatsink to the LM2596 chip?\u003c\/strong\u003e\u003cbr\u003e\nA: If you are continuously drawing 2 Amps or less, the module dissipates heat efficiently enough on its own. If you plan to draw between 2A and the maximum 3A continuously, you must attach a small aluminum heatsink to the LM2596 chip to prevent thermal shutdown.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How do I change the output voltage?\u003c\/strong\u003e\u003cbr\u003e\nA: Connect your input power source, attach a multimeter to the output pads, and use a small flathead or Phillips screwdriver to turn the tiny brass screw on the top of the blue potentiometer block. It is a multi-turn trimpot, so it may take several full rotations before you see the voltage begin to change.\u003c\/p\u003e","brand":"Tomson Electronics","offers":[{"title":"Default Title","offer_id":49552956424430,"sku":"SEN-29138","price":59.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/LM_2596_STEP_DOWN_MODULE_ADJ_IMP.avif?v=1788874746","url":"https:\/\/www.tomsonelectronics.com\/products\/lm2596-dc-dc-adjustable-step-down-buck-converter-module-3a","provider":"Tomson Electronics ","version":"1.0","type":"link"}
