MT3608 2A DC-DC Step-Up Boost Converter Power Module

MT3608 2A DC-DC Step-Up Boost Converter Power Module

The MT3608 is a highly efficient, compact DC-DC step-up converter capable of boosting input voltages from as low as 2V up to an adjustable 5V–28V output. Delivering a maximum current of up to 2A with an impressive 93% efficiency, this module is an essential power regulation component for any workbench.

At Majestronicz, we know that reliable power is the foundation of a stable circuit. The MT3608 utilizes a high-frequency (1.2MHz) switching architecture, allowing for the use of small, low-ESR ceramic capacitors. This guarantees a highly compact footprint without sacrificing performance or longevity. Whether you are stepping up a 3.7V lithium-ion cell to power a 5V microcontroller, or boosting a 5V USB source to run 12V peripherals, this module provides a clean and stable power supply

Built-in over-current and thermal shutdown protections ensure that your circuit remains safe, even under demanding load conditions.

Key Features

• High Efficiency: Up to 93% conversion rate for minimal heat and power loss.

• recision Control: Onboard multi-turn potentiometer for exact voltage adjustments.

• Built-in Protection: Integrated thermal overload and over-current limiting safeguard your sensitive electronics.
• Ultra-Compact Design: Easily fits into space-constrained DIY enclosures, robotics chassis, and breadboard layouts.

⚠️ Important Usage Notes (Please Read Before Powering):

Potentiometer Adjustment: Upon first use, the potentiometer may require 15 to 20 full counter-clockwise turns before the output voltage begins to step up.

Input vs. Output: As this is a boost converter, the input voltage must always remain lower than your desired output voltage.

Current Draw: Remember that as you increase the voltage, the available current drops. For maximum lifespan, avoid drawing the full 2A continuously without active cooling.
