Type-C Boost Converter Module 2A (MT3608)

The Type-C Boost Converter Module (MT3608) is a compact DC-DC step-up voltage regulator designed to increase a lower DC input voltage to a higher, adjustable output voltage.

Unlike conventional boost modules that require direct wire connections for power input, this version includes a USB Type-C connector, allowing it to receive 5V power from a suitable USB adapter or power bank.

Built around the MT3608 switching regulator, the module features an adjustable potentiometer, an onboard inductor and clearly marked solder terminals. It is suitable for electronic experiments, portable power supplies, robotics and DIY voltage conversion projects.

Technical Specifications

Applications

1. USB-Powered Adjustable Power Supply

Convert a suitable 5V USB power supply into a higher adjustable DC voltage for low-power electronics experiments.

For example, the module can be adjusted to provide 9V or 12V from a suitable 5V USB input, provided the connected load remains within its power capability.

2. Arduino and Robotics Projects

Provide suitable boosted DC voltages for electronic peripherals, small motors and other low-power equipment that require a higher voltage than the available supply.

3. Battery-Powered Electronics

Increase the voltage from a compatible battery pack to power low-current electronic devices.

DIYGH stocks 18650 Li-ion Rechargeable Batteries 3.7V 2500mAh for portable electronics projects. Battery-powered circuits should use suitable charging and protection arrangements.

4. Portable Power Supply Projects

Build compact adjustable DC power supplies for testing sensors, electronic circuits and small devices.

5. Electronics Education

Demonstrate boost conversion, switching voltage regulation, efficiency and the relationship between input and output power.

How the Type-C Boost Converter Module Works

The MT3608 is a switching step-up voltage converter.

It stores energy in an inductor and transfers that energy to the output through a controlled switching process. The regulator adjusts its switching operation to maintain the selected output voltage.

The onboard potentiometer controls the voltage setting.

For example:

• 5V input to 9V output
• 5V input to 12V output
• 9V input to 15V output
• 12V input to 24V output

These are possible voltage settings, not guarantees of a particular output current. Available power depends on the supply, conversion efficiency and connected load.

Input and Output Connections

The Type-C connector and VIN terminals provide alternative ways to supply input power. Use one input source at a time.

Important: The USB-C connector is a power input only. This module does not charge batteries or negotiate higher USB Power Delivery voltages.

How to Adjust the Output Voltage

1. Connect a suitable regulated DC power supply to the USB-C port or VIN terminals.
2. Leave the output load disconnected.
3. Connect a multimeter across OUT+ and OUT-.
4. Turn the blue potentiometer gradually while observing the output voltage.
5. Continue adjusting until the required voltage is obtained.
6. Confirm that the output voltage and polarity are correct.
7. Connect the intended load and verify that the voltage remains stable.

The potentiometer may require several complete turns before the output begins changing.

For accurate voltage measurements, use the ANENG XL830L Digital Multimeter available at DIYGH.

Understanding the 2A Rating

The module is advertised with a maximum output current of 2A, but this should not be interpreted as a guaranteed continuous current at every output voltage.

As the output voltage increases, the current available from a limited input power source decreases.

For example, boosting 5V to 12V requires the input source to deliver more current than the output load consumes, accounting for conversion losses.

For practical applications, keep the output load within the module’s thermal and power capabilities.

MT3608 vs XL6009 Boost Converter

The MT3608 Type-C module is particularly convenient for compact, lower-power projects and experiments powered from a USB supply.

For applications requiring a different input-voltage range and a larger boost converter design, DIYGH also stocks the XL6009 DC-DC Adjustable Step-Up Boost Converter Module.

Boost Converter vs Buck Converter

A boost converter increases DC voltage. It cannot regulate the output below the input voltage.

If your project requires reducing voltage, such as converting 12V to 5V, use a step-down converter instead.

For this purpose, DIYGH stocks the LM2596 DC-DC Adjustable Buck Converter Module.

Important Usage Information

• The output voltage must be higher than the input voltage.
• Do not exceed the 24V maximum DC input rating.
• Use a regulated 5V supply through the USB Type-C connector.
• Always check the output voltage before connecting sensitive electronics.
• Ensure the connected load does not exceed the available input power.
• Avoid excessive loading and overheating.
• Do not connect the module directly to AC mains.
• This is a voltage boost converter, not a lithium battery charger or dedicated constant-current LED driver.
• Use suitable wiring and insulation for the intended circuit.
