MT3608 2A Max DC-DC Step Up Power Module Booster Power Module

Description

Description

The MT3608 2A DC-DC Step-Up Boost Converter Module is a compact and highly efficient power solution designed to elevate lower DC voltages to higher, usable levels. Whether you need to power a 12V LED strip from a 5V USB port, run an Arduino project from a single 3.7V lithium battery, or create a custom power bank, this tiny module is an essential tool for any electronics workbench.

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 high frequency allows the module to use small, low-profile inductors and ceramic capacitors, resulting in a compact form factor without sacrificing performance .

How It Works:
As a dedicated “Boost” converter, the MT3608 module only steps voltage up. It takes an input voltage (from 2V to 24V) and efficiently increases it to a higher, adjustable output voltage (up to 28V) . It works by rapidly switching the current through an inductor to build a magnetic field, then releasing that stored energy at a higher voltage.

High Efficiency & Power:
With an efficiency rating of up to 93-97% , the module wastes very little energy as heat, making it ideal for battery-powered applications. It features an internal 4A switch current limit and an 80mΩ power MOSFET, allowing it to handle peak output currents of up to 2A .

Adjustability & Protection:
Adjusting the voltage is simple using the onboard multi-turn potentiometer, allowing you to fine-tune your exact voltage output (e.g., 5V, 9V, 12V, or 24V). The MT3608 chip also includes built-in safety features such as over-current limiting and thermal shutdown to protect your circuit from accidental shorts or excessive loads .

Note: Because the output voltage must always be higher than the input, this module is not suitable for “stepping down” voltage (e.g., converting 12V to 5V).

Whether you are a hobbyist powering a portable speaker, an IoT developer needing a 5V rail from a battery, or a professional creating a custom power supply, the MT3608 provides a simple, reliable, and low-cost solution for all your voltage boosting needs.
