Note: 1. Voltage of EN and voltage of VIN should be different, or it may cause unstable output. 2.For low voltage input, user needs to refer to the curve of output derating use. Package Includes:±15V Dual Output Power Converter x1 Review: I needed a reliable and stable 5V voltage source to power an Arduino board and some small electronics on my truck. This was a cost-effective solution, taking my ~12V truck voltage and converting it to 5.0V. It's a good form factor, operates efficiently and dissipates minimal heat. I'm quite pleased with it. Review: To get this supply quiet enough for audio use I had to pre-load it with about 70 mA. With a 140 mA total load the input start-up current was about 2.3A for approximately 50 ms and would over-current trigger almost all 12V 2A 24W switcher's outputs despite the load being only about 4W. The 12V input current, when operating, was around 400 mA. With only the 70 mA load the peak current was about 3.3A. For reliable operation a 12V 4A switcher is required for start-up: It takes a 48W switcher to deliver 4W output despite its near 85% efficiency. A 24V input supply does not reduce the peak current - it only shortens the duration. An unregulated linear 12V wall mount supply will likely be more tolerant of the start-up current. For this reason I'm giving it 4 stars. ## Features - DROK micro voltage converter with low voltage input range DC 4.8-35V, positive and negative dual output voltage is ±15V, rated output current is 660mA. - APPLICATION: the step-up regulator module is suitable for sensor, operational amplifier, audio and other devices that needs positive-negative power output. - SMALL MODULE HIGH EFFICIENCY: DROK boost converter is with small dimension 64x27.5x12.5mm; the small module conversion rate can be up to 88%. - TWO MOUNT METHODS: the volt transformer module not only support row pin welding, but also lead mounting, which will be convenient for your use. - NOTE: please note that although the module is with short circuit protective function, it can not in long continuous short circuit, or it will be damaged. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0752TRXDC | | Brand Name | DROK | | Current Rating | 660 Milliamps | | Customer Reviews | 4.3 4.3 out of 5 stars (60) | | Item Dimensions D x W x H | 13D x 28W x 13H millimeters | | Item Weight | 1.02 Ounces | | Manufacturer | DROK | | Maximum Frequency | 80 MHz | | Model | 2001708005 | | Mounting Type | Rack Mount, Chassis Mount | | Part Number | 2001708005 | | Power Source | DC | | Specification Met | RoHS | | Unit Count | 1.0 Count | ## Product Details - **Brand:** DROK - **Current rating:** 660 Milliamps - **Mounting type:** Rack Mount, Chassis Mount - **Power source:** DC - **Product dimensions:** 13D x 28W x 13H millimeters ## Images ![Micro Dual Power Supply - DC to DC Buck Boost Converter 4.8-35V to ±15V Positive Negative Dual Output, Step Up Voltage Regulator for OP-Amps - Image 1](https://m.media-amazon.com/images/I/71-S2D3vytL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by R***S on 12 March 2025* I needed a reliable and stable 5V voltage source to power an Arduino board and some small electronics on my truck.

Operates and buck or boost over wide range, providers ground-referenced +/- 15 vdc. Remarkably low ripple at the output, better than my cheap Chinese variable supply with current limit. The controller chip labeling has been scraped off, but probing the switch pins it's clearly a flyback regulator similar to LM2587 (different pinouts) attached to a transformer. It requires a minimum load of 30 mA, and with 1/2 watt resistors they still reach 70 decrees C... BE CAREFUL! Update: I was working on an op-amp project and my cheap adjustable supply blew a capacitor, got 2 volts ripple on the output. I took this DROK module and fed it with 2x 18650 batteries and was back in business! +-15 volts from 2x18650s, love it! ## Frequently Bought Together - DROK Micro Dual Power Supply - DC to DC Buck Boost Converter 4.8-35V to ±15V Positive Negative Dual Output, Step Up Voltage Regulator for OP-Amps - Boost Buck Voltage Converter, DC-DC 5V-24V to +/-3V-30V Step UP Down Power Supply Module Adjustable 20W Positive Negative Dual Output Voltage Charging Converter for Amplifier - DC-DC Positive & Negative Voltage Boost-Buck Converter (Output Voltage ±5VDC) --- ## 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.gr/products/264052546-micro-dual-power-supply-dc-to-dc-buck-boost-converter](https://www.desertcart.gr/products/264052546-micro-dual-power-supply-dc-to-dc-buck-boost-converter) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-04-23*
