Suitable for various electronic projects. - 【Input Voltage】DC 4V to 38V (input voltage must be 1.5V higher than the output voltage, no boost). - 【Output Voltage】DC 1.25V to 36V voltage is continuously adjustable, maximum output current is 5A. - 【Mini Size】62*38*14 mm (with potentiometer). 2 sets included. - 【Easy to DIY】Connect to power source, using a mini screwdriver to increase or decrease output voltage by adjusting the screw on the blue potentiometer and monitor voltage with multimeter to get the needed voltage, clockwise to step up voltage and counterclockwise to step-down voltage. (Factory default stays a high voltage, you need to contrarotate about 7-15 circles before the voltage starts ramping down, 1 circle means +/- 1V) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B085T73CSD | | Best Sellers Rank | #125,468 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #496 in Power Converters | | Brand Name | Valefod | | Current Rating | 5 A | | Customer Reviews | 4.3 4.3 out of 5 stars (333) | | Item Dimensions D x W x H | 2.44"D x 1.5"W x 0.55"H | | Item Weight | 32 g | | Manufacturer | Valefod | | Maximum Frequency | 180 KHz | | Minimum Frequency | 180 KHz | | Model | VA-0189 | | Mounting Type | PCB Mount | | Number of Items | 1 | | Number of Packs | 2 | | Part Number | VA-0189 | | Specification Met | RoHS | | UPC | 722453988321 | ## Product Details - **Brand:** Valefod - **Current Rating:** 5 A - **Mounting Type:** PCB Mount - **Product Dimensions:** 2.44"D x 1.5"W x 0.55"H - **Specification Met:** RoHS ## Images ![[2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display - Image 1](https://m.media-amazon.com/images/I/51wsSDUnXgL.jpg) ![[2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display - Image 2](https://m.media-amazon.com/images/I/51jF5E6851L.jpg) ![[2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display - Image 3](https://m.media-amazon.com/images/I/51PD1K96W7L.jpg) ![[2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display - Image 4](https://m.media-amazon.com/images/I/51uQAjvB8KL.jpg) ![[2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display - Image 5](https://m.media-amazon.com/images/I/41DvKhcFiqL.jpg) ## Frequently Bought Together - [2 Pack] DC-DC 5A Buck Converter 4-38V to 1.25-36V Step-Down Voltage Regulator High Power Module with LED Display - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - ELEGOO MEGA R3 Board ATmega 2560 + USB Cable Compatible with Arduino IDE Projects RoHS Compliant --- ## 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.pt/products/204266302-2-pack-dc-dc-5a-buck-converter-4-38v-to](https://www.desertcart.pt/products/204266302-2-pack-dc-dc-5a-buck-converter-4-38v-to) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-09-04*
