The MT3608 boost converter is a budget-friendly, highly efficient DC-DC step-up module that enables users to boost a 2V to 24V input voltage to a 5V to 28V output at a maximum of 2A. DC-DC boost converters raise the input voltage to a higher level while simultaneously decreasing the available current, as the module cannot output more power than it receives.
This mt3608 module is adjustable and can generate a voltage within the 5.0V to 28V range, providing a continuous current of up to 1.5A (with 1A being highly stable in most configurations). The input voltage must always be lower than the output voltage, as the device operates strictly as a step up module.
The MT3608 converter IC integrates over-current and thermal limiting features to safeguard against device failure during excessive stress. Furthermore, it utilizes low ESR bulk ceramic capacitors instead of electrolytic ones, eliminating long-term aging concerns and contributing to its ultra-compact design.
Adjusting the mt3608 is simple using the onboard blue potentiometer.
Note: Always adjust with no load connected for the most accurate reading.
Choosing the right dc-dc boost converter depends on your current needs. The MT3608 is ultra-compact and ideal for low-power applications up to 2A (1.5A continuous). If your project demands higher current (up to 4A–5A) or handles heavier loads, you should upgrade to the XL6009 Boost Module. Conversely, if you need to lower voltage, consider the LM2596 DC-DC Buck Module as your step-down alternative.
The most popular application for this step up module is converting a single 3.7V Li-ion or Li-Po battery to a stable 5V output. This is perfect for powering Arduino boards, 5V sensors, or small DC motors from a portable battery. For safely charging the 3.7V battery in these setups, pair this module with a TP4056 Battery Charger Module.

The DC-DC step-up converter known as the MT3608 module has the capability to increase output voltages to a maximum of 28V, while being able to handle input voltages as low as 2V. This module is typically employed in settings where the voltage demands do not surpass 28V and current requirements remain below 2A. The MT3608 converter is designed for small, low-power applications, and employs a constant frequency, 6-pin SOT23 current mode step-up converter. With a switching frequency of 1.2MHz, the device permits the usage of diminutive, cost-effective capacitors and inductors to reduce the overall module size. Its primary function is to elevate a low input voltage to a usable higher output voltage.
The MT3608 boost converter can output up to 28V
The MT3608 is a DC-DC boost module capable of producing an output current of up to 1.5A. The module features safeguards such as under-voltage lockout, current limiting, and thermal overload protection to avert damage in the case of output overload. However, certain users have noted that the module becomes excessively hot and can only sustain output current levels of up to 1A. Conversely, other sources assert that the MT3608 can provide a maximum output current of 2A. It is important to note that the current limit of the MT3608 may differ based on the specific module and the conditions under which it operates.
The MT3608 starts from about 2V input and boosts up to about 28V. For stable output at load, feed at least 3V, such as a single Li-ion cell.
Connect the Li-ion cell to VIN+ and VIN-, measure VOUT with a multimeter and turn the trimpot until it reads 12V. Keep output current under about 300 to 500mA at 12V from a single cell.
