Description
The Adjustable DC-DC USB Boost Converter Module is a compact and highly efficient power solution designed to elevate standard 5V USB voltage to higher, adjustable output levels. Whether you need to power a 12V LED strip from a power bank, run a 9V pedal from a USB port, or create a variable desktop power supply, this tiny module delivers reliable performance in a convenient USB stick form factor.
At the heart of this module is the MT3608 chip – a constant frequency, current mode step-up converter that operates at a high 1.2MHz switching frequency . This advanced design integrates an 80mΩ power MOSFET and supports up to 2A output current, making it ideal for small to medium power applications .
How It Works: As a dedicated “Boost” converter, this module only steps voltage up. It takes a standard 5V USB input and efficiently increases it to a higher, adjustable output voltage ranging from approximately 6V up to 28V . The onboard multi-turn potentiometer allows you to dial in common voltages such as 9V, 12V, 15V, 18V, or 24V with a simple screwdriver turn .
Key Design Benefits:
-
Plug-and-Play Convenience: Built-in Micro USB or USB Type-C input port allows direct connection to any USB charger, power bank, or computer port
-
High Efficiency: Up to 93-97% conversion efficiency minimizes power loss and heat generation
-
Compact Form Factor: Small enough to fit inside most project enclosures or plug directly into a USB port
-
Adjustable Output: Multi-turn potentiometer allows precise voltage setting from ~5V to 28V
Important Operating Note: This is a step-up (boost) converter only. The output voltage must be set higher than the input voltage (typically at least 2V higher). It cannot step down voltage – for example, you cannot use it to convert 12V to 5V .
Whether you are a hobbyist powering portable electronics, an IoT developer needing a 12V rail from a USB power bank, or a professional creating a custom bench power supply, this USB boost converter module provides a simple, reliable, and low-cost solution for all your voltage boosting needs.
