2A DC-DC Boost Converter Module – Wide Input Voltage 2-24V to Adjustable 5V/9V/12V/28V Output, MT2577 Chip, Micro USB Interface

Description

Description

The 2A DC-DC 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 supply for your electronics projects, this tiny module is an essential tool for any workbench.

This module accepts a wide input voltage range of 2V to 24V DC and boosts it to an adjustable output voltage from 5V up to 28V DC . The output voltage is easily set using the onboard precision potentiometer, allowing you to dial in common voltages such as 5V, 9V, 12V, 15V, or 24V with a simple screwdriver turn .

A standout feature of this module is the Micro USB interface integrated directly onto the board . This allows you to power the module from common USB sources such as phone chargers, power banks, or computer USB ports without needing to solder wires to the input pads. Simply connect a standard micro USB cable, and you can generate 9V, 12V, or higher voltages from a 5V USB source .

At the heart of this module is the MT2577 (or functionally equivalent MT3608) step-up converter chip. This chip operates at a high 1.2MHz switching frequency, allowing the module to use small, low-profile components while maintaining high efficiency . The module features an internal 4A switch current limit, enabling peak output currents of up to 2A (1A recommended for continuous use without additional cooling) .

How It Works: As a dedicated “Boost” converter, this module only steps voltage up. It works by rapidly switching current through an inductor to build a magnetic field, then releasing that stored energy at a higher voltage. 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).

Important Operating Note: The output voltage must always be greater than the input voltage. If the input voltage exceeds the set output voltage, the module cannot regulate down, and the output will roughly follow the input voltage, which may damage your connected load.

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, this MT2577-based boost converter module provides a simple, reliable, and low-cost solution for all your voltage boosting needs.
