MT3608 Description
The MT3608 is a 6-pin SOT23 constant frequency current mode step-up converter designed for low-power applications. The MT3608 operates at 1.2MHz and enables the use of small, low-cost capacitors and inductors with a height of 2mm or less. Internal soft-start reduces inrush current and hence increases battery life.
MT3608 Pinout

MT3608 Pinout
| PIN | NAME | FUNCTION |
| 1 | SW | Power Switch Output. SW is the drain of the internal MOSFET switch. Connect the power inductor and output rectifier to SW. SW can swing between GND and 28V. |
| 2 | GND | Ground Pin |
| 3 | FB | Feedback Input. The FB voltage is 0.6V. Connect a resistor divider to FB. |
| 4 | EN | Regulator On/Off Control Input. A high input at EN turns on the converter, and a low input turns it off. When not used, connect EN to the input supply for automatic startup. |
| 5 | IN | Input Supply Pin. Must be locally bypassed. |

Specifications
- TypeParameter
- Package / Case
refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.
SOT-23-6 - Packaging
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
Tape & Reel (TR) - Function
The parameter "Function" in electronic components refers to the specific role or purpose that the component serves within an electronic circuit. It defines how the component interacts with other elements, influences the flow of electrical signals, and contributes to the overall behavior of the system. Functions can include amplification, signal processing, switching, filtering, and energy storage, among others. Understanding the function of each component is essential for designing effective and efficient electronic systems.
Step-Up - Number of Outputs1
- Voltage - Input (Max)
Voltage - Input (Max) is a parameter in electronic components that specifies the maximum voltage that can be safely applied to the input of the component without causing damage. This parameter is crucial for ensuring the proper functioning and longevity of the component. Exceeding the maximum input voltage can lead to electrical overstress, which may result in permanent damage or failure of the component. It is important to carefully adhere to the specified maximum input voltage to prevent any potential issues and maintain the reliability of the electronic system.
24V - Output Type
The "Output Type" parameter in electronic components refers to the type of signal or data that is produced by the component as an output. This parameter specifies the nature of the output signal, such as analog or digital, and can also include details about the voltage levels, current levels, frequency, and other characteristics of the output signal. Understanding the output type of a component is crucial for ensuring compatibility with other components in a circuit or system, as well as for determining how the output signal can be utilized or processed further. In summary, the output type parameter provides essential information about the nature of the signal that is generated by the electronic component as its output.
Adjustable - Voltage - Input (Min)
Voltage - Input (Min) refers to the minimum voltage level that an electronic component requires to operate correctly. It indicates the lowest voltage that can be applied to the component while still allowing it to function as intended. If the input voltage falls below this specified minimum, the component may not perform properly or may fail to operate altogether. This parameter is critical for ensuring reliable operation and longevity of the device in electronic circuits.
2V - Output Configuration
Output Configuration in electronic components refers to the arrangement or setup of the output pins or terminals of a device. It defines how the output signals are structured and how they interact with external circuits or devices. The output configuration can determine the functionality and compatibility of the component in a circuit design. Common types of output configurations include single-ended, differential, open-drain, and push-pull configurations, each serving different purposes and applications in electronic systems. Understanding the output configuration of a component is crucial for proper integration and operation within a circuit.
Positive - Topology
In the context of electronic components, "topology" refers to the arrangement or configuration of the components within a circuit or system. It defines how the components are connected to each other and how signals flow between them. The choice of topology can significantly impact the performance, efficiency, and functionality of the electronic system. Common topologies include series, parallel, star, mesh, and hybrid configurations, each with its own advantages and limitations. Designers carefully select the appropriate topology based on the specific requirements of the circuit to achieve the desired performance and functionality.
Boost - Frequency - Switching
"Frequency - Switching" in electronic components refers to the rate at which a device, such as a transistor or switching regulator, turns on and off during operation. This parameter is crucial in determining the efficiency and performance of power converters, oscillators, and other circuits that rely on rapid switching. Higher switching frequencies typically allow for smaller component sizes but may require more advanced design considerations to manage heat and electromagnetic interference.
1.2MHz - Voltage - Output (Max)
Voltage - Output (Max) is a parameter that specifies the maximum voltage level that can be delivered by an electronic component, such as an integrated circuit or a power supply. It indicates the highest voltage that the component is designed to provide at its output terminal under normal operating conditions. This parameter is crucial for determining the compatibility of the component with other parts of the circuit and ensuring that the voltage requirements are met for proper functionality. Designers and engineers use this specification to ensure that the component can safely deliver the required voltage without exceeding its maximum output capability.
28V - RoHS Status
RoHS means “Restriction of Certain Hazardous Substances” in the “Hazardous Substances Directive” in electrical and electronic equipment.
RoHS Compliant

Where to Use MT3608
The MT3608 can be utilized in applications that require a voltage of less than 28V and a current of less than 2A. As a result, this module is best suited for portable devices such as power banks and portable power sources. It can also be utilized in educational projects due to its inexpensive cost.
How to Use MT3608
You can connect an input voltage ranging from 2V to 24V DC to the MT3608. A battery, a solar cell, or any other accessible source can be used as the input source. After connecting the input voltage, connect a digital multimeter to the output voltage points of the module and pick above 28V from the digital multimeter voltage selection panel. Adjust the variable resistor until the multimeter shows your desired output voltage.
