Each module delivers up to 3A peak current with 10W power capacity, featuring built-in short circuit protection and enable control. Its tiny size and versatile fixed or adjustable voltage options make it ideal for professional-grade electronics projects requiring reliable, efficient power conversion. ## Description DROK DC 12 Volt to 5 Volt Converter Set of 5 Parameters Type: Non-isolated step-down module (synchronous rectification) Input voltage: DC 4.5-20V Output voltage: Integrated adjustable and fixed output, fixed output voltage can be selected on the back Adjustable range: 1-16V; Fixed voltage: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V Output current: Max 3A (peak: 3A, long-term: within 2A) Power: 10W Conversion efficiency: Up to 97% (typical value: >90% when 12V turns to 5V 2A) Switching frequency: 800KHz Output ripple: typical value 20mV Working temperature: -40℃ to +85℃ (the higher the ambient temperature, the smaller the output power) Output overvoltage protection: None No-load current: <1 mA Load regulation rate: ±2% Voltage adjustment rate: ±2% Dynamic response speed: 5% 200uS Output short circuit protection: Yes, but please do not keep short circuit for a long time Input reverse connection protection: None Enable control: Yes, high level work, low level stop work, high level is 2-5V, low level is about 0V. Default internal with pull - up to input positive pole. Wiring method: Welding Input method: Welding Output method: Welding/pin header Welding hole spacing: 2.54 mm Package Includes: 5 x mini buck converter 5v ## Features - Parameter --- For DROK mini buck converter, Input voltage: DC 4.5-20V; Output voltage can be adjustable or fixed. Adjustable range: 1-16V; Fixed voltage: 1.8V, 2.5V, 3.3V, 5V, 9V, 12V; Output current: Max 3A (peak: 3A, long-term: within 2A); Power: 10W. - High Efficiency --- Conversion efficiency: Up to 97% (typical value: >90% when step down 12V to 5V 2A). - Output Voltage Adjustable or Fixable --- These tiny 12v to 5v step down converters can be variable at output voltage. The small board is default to be used for output voltage adjustment. If you want to get fixed voltage output, you need to cut off the Pad A by using a sharp thing such as a knife then weld together the port of the fixed voltage you want. - Protection and Enable Control --- Output short circuit protection, but please do not keep short circuit for a long time. The integrated enable port defaults the working mode and it will be off when it is at low electric level off, which bring a great convenience for users. - NOTE --- This mini buck converter is really very tiny, much smaller than a 1-dollar coin, nearly a half of the coin. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B096RC71DC | | Best Sellers Rank | #40,668 in Tools & Home Improvement (See Top 100 in Tools & Home Improvement) #138 in Power Converters | | Brand | DROK | | Color | Black | | Customer Reviews | 4.2 4.2 out of 5 stars (699) 4.2 out of 5 stars | | Input Voltage | 20 volts | | Item Highlight | Mini Adjustable Voltage Regulator DC 4.5-20V to 6 Different Output Voltage Step Down Converter 3A 10W for Microcontroller | | Manufacturer | DROK | | Model Number | DROK-DC-DC-5V | | Number Of Items | 5 | | Number Of Outlets | 5 | | Number Of Packs | 5 | | Output Voltage | 5 volts | | Plug Type | Type B | | Power Source | Corded Electric | | Warranty Description | 1 YEAR | ## Product Details - **Brand:** DROK - **Color:** Black - **Input Voltage:** 20 volts - **Output Voltage:** 5 volts - **Plug Format:** Type B ## Images ![DROK 1.8V/2.5V/3.3V/12V/9V/5V Buck Converter Adjustable Pack of 5 - Image 1](https://m.media-amazon.com/images/I/71AZ2j+nf2L.jpg) ![DROK 1.8V/2.5V/3.3V/12V/9V/5V Buck Converter Adjustable Pack of 5 - Image 2](https://m.media-amazon.com/images/I/71n0xRrs5ZL.jpg) ![DROK 1.8V/2.5V/3.3V/12V/9V/5V Buck Converter Adjustable Pack of 5 - Image 3](https://m.media-amazon.com/images/I/71G2+HN7+0L.jpg) ![DROK 1.8V/2.5V/3.3V/12V/9V/5V Buck Converter Adjustable Pack of 5 - Image 4](https://m.media-amazon.com/images/I/81PgV0EWZJL.jpg) ![DROK 1.8V/2.5V/3.3V/12V/9V/5V Buck Converter Adjustable Pack of 5 - Image 5](https://m.media-amazon.com/images/I/71X50Ntz1+L.jpg) ## Available Options This product comes in different **Color, Number of Items** options. --- ## 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.com.ar/products/353569481-drok-1-8v-2-5v-3-3v-12v-9v-5v](https://www.desertcart.com.ar/products/353569481-drok-1-8v-2-5v-3-3v-12v-9v-5v) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-10-29*
