Overview The MT3608-2A is a small and efficient DC-DC boost converter that increases lower voltages to higher output levels. It includes a USB-C input connector for simple powering and can boost voltages from as low as 2 V up to 28 V. It is suitable for battery-powered devices, portable circuits, LED drivers, and general prototyping where a stable higher voltage is needed. Key features Input voltage 2 - 24 V DC (compatible with USB-C power sources) Adjustable output voltage up to 28 V Up to 2 A peak output current (around 1 A continuous depending on load and cooling) Efficiency up to 94 % Boost conversion type (step-up) Onboard potentiometer for voltage adjustment Compact PCB with integrated USB-C connector Typical module size around 36 x 17 x 7 mm Recommended applications Powering 12 V fans, LEDs, or sensors from 5 V sources Boosting Li-ion or NiMH battery voltage for portable circuits Breadboard and prototyping power supply DIY tools and small electronics projects Emergency or backup voltage boosting Technical specification Parameter Value Input voltage 2 - 24 V DC Output voltage Up to 28 V (adjustable) Output current Up to 2 A peak, ~1 A continuous Efficiency Up to 94 % Conversion type Boost (Step-Up) Connector USB-C input Dimensions ~36 x 17 x 7 mm Safety and notes Always calibrate the output voltage before use. Connect a 1 kΩ – 10 kΩ resistor to the output, measure the voltage, and adjust it with the potentiometer before connecting sensitive electronics. Do not short the output or exceed the maximum current. Output voltage increases as you turn the potentiometer clockwise; measure before connecting loads. Heat increases at higher currents, so airflow or heatsinking may be needed at heavy loads.
