With an input voltage range of 4 to 40V and adjustable output from 1.25 to 35V, it caters to a variety of electronic projects. Its robust design supports up to 3A output with thermal protection, making it ideal for both hobbyists and professionals. ## Description This is LM2596 2A Buck Step-down Power Converter Module DC 4.0~40 to 1.3-37V, it comes with a built-in voltmeter display and uses an advanced microcontroller. This version of LM2596 DC-DC step-down (buck) power supply module includes the very useful addition of an integrated digital voltage meter. The voltage meter is capable of sensing both input and output supply voltages and can be quickly switchable between the two by pressing a voltage selection button on the module. Together with its high precision multi-turn potentiometer, this means any desired output voltage within its supply range can be set without the need for an external voltage meter. The module also boasts a very high operating range with a DC input supply range of 4 – 35V and an adjustable output range of 1.3 – 35V. In addition to its voltage range, it has a high output current capability of up to 2A. Connection to the module is provided with the option of both input and output screw terminals or large solderable pads if a more permanent connection is required. ## Features - Input Voltage:+4 to 40vdc - Output Voltage:+1.25 to 35vdc - Output Current: 2A Rated, ( 3A maximum with heat sink ) - Switching Frequency: 150kHz - Built-in output short protection function & The built-in thermal shutdown function ## Images ![SunRobotics LM2596 DC-DC Buck Converter Adjustable Step-Down Power Supply Module with Digital Voltmeter Display - Image 1](https://m.media-amazon.com/images/I/310TS8Zq+ML.jpg) ![SunRobotics LM2596 DC-DC Buck Converter Adjustable Step-Down Power Supply Module with Digital Voltmeter Display - Image 2](https://m.media-amazon.com/images/I/31C1AIS1ldL.jpg) ![SunRobotics LM2596 DC-DC Buck Converter Adjustable Step-Down Power Supply Module with Digital Voltmeter Display - Image 3](https://m.media-amazon.com/images/I/21u-pS8ws7L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Not working not up down volt *by A***F on Reviewed in India 🇮🇳 on 17 September 2022* Not working properly not up down volt not working properl ### ⭐⭐ 2.0 out of 5 stars Bad product *by A***R on Reviewed in India 🇮🇳 on 27 July 2022* Verry bad experience --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/245667851-sunrobotics-lm2596-dc-dc-buck-converter-adjustable-step-down-power](https://www.desertcart.pl/products/245667851-sunrobotics-lm2596-dc-dc-buck-converter-adjustable-step-down-power) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-22*
