MT3608 2V-24V Input to 5V-28V Output 2A DC-DC Step Up Boost Converter Module

📋 Overview

The MT3608 is a compact, high-efficiency step-up (boost) DC-DC converter module designed to increase low input voltages to higher output voltages. It accepts any input from 2V to 24V and boosts it to an adjustable output of up to 28V, making it ideal for battery-powered and low-power applications. An onboard potentiometer lets you set the exact output voltage you need, and built-in protections (under-voltage lockout, current limiting, and thermal overload) help keep your project safe.

⚠️ Important: This is a boost (step-up only) converter — the output voltage must always be higher than the input voltage. Do not exceed 24V input or 28V output. Maximum output power is 10W.

⭐ Key Features

• Input Voltage: 2V – 24V DC via solder pads
• Adjustable Output: 5V – 28V via onboard potentiometer
• Output Current: Up to 2A peak
• Maximum Output Power: 10 Watts
• High Efficiency: Up to 97%, typically 93% at Vout=12V, Vin=5V, Iout=200mA
• High Switching Frequency: 1.2 MHz (constant frequency, current-mode control)
• Built-in Protections: Under-voltage lockout, current limiting, thermal overload
• Automatic PFM Mode: Switches to pulse frequency modulation at light loads for improved efficiency
• Internal Soft-Start: Minimizes inrush current on power-up
• Ultra-Compact Size: Tiny 36 × 17 × 12 mm (1.42 × 0.67 × 0.47 in) PCB for embedded use

📊 Specifications

📌 Pinout

🚀 Getting Started

1. Connect Vin+ and Vin− to a 2V–24V DC power supply or battery.
2. With the output disconnected from your load, attach a multimeter to Vout+ and Vout− (DC voltage mode).
3. Adjust the potentiometer to set the desired output voltage. Turn counter-clockwise to increase voltage. You may need to turn it many turns initially to reach the operating range.
4. Once the multimeter reads your desired voltage, connect your load to Vout+ and Vout−.
5. Verify the output voltage under load and fine-tune the potentiometer if needed.

🎯 Applications

• Battery voltage boosting for portable electronics
• LED strip drivers (12V strips from lower-voltage batteries)
• IoT sensor node power supplies
• Arduino / Raspberry Pi project power rails
• Solar panel voltage boosting
• Portable instrument and test equipment power
• Charging higher-voltage battery packs from low-voltage sources

⚠️ Important Notes

• This is a boost-only converter — output voltage must always be higher than input voltage.
• Do not exceed 24V input or 28V output.
• Do not exceed 2A output current or 10W output power.
• The potentiometer turns counter-clockwise to increase voltage — opposite of many other converter modules.
• Input power must be greater than output power plus ~10% for conversion losses. Always verify your input source can deliver sufficient current.
• Allow adequate airflow around the module when operating near maximum power.
• Disconnect power before making any wiring changes.
