Test review of 2A DC-DC Step up boost converter MT3608
MT3608 is a high-efficiency 1.2MHz 2A step-up converter. This article mainly covers datasheet, schematics, power, circuit, and more details about the MT3608 boost converter. Furthermore, there is a huge range of semiconductors, capacitors, resistors, and Ics in stock. Welcome your RFQ!
MT3608
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.
| 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. |
| 6 | NC | NC |

MT3608 Application Circuit
MT3608 Efficiency
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.
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.
