What is MT3608? — More than just a “small circuit board”

First, it’s important to clarify: The MT3608 is fundamentally a synchronous rectification boost DC-DC converter chip. What we commonly refer to as the “MT3608 boost board” is actually a “modular product” that integrates the MT3608 chip with peripheral components such as inductors, capacitors, and resistors. This modular design significantly lowers the user’s entry barrier, eliminating the need for complex soldering of peripheral circuits. Users simply connect the input power source and load to achieve voltage step-up functionality.

Core Advantages of MT3608

Ultra-compact size: The common MT3608 module measures only about 20mm × 15mm (roughly the size of a fingernail), enabling seamless integration into small devices such as Bluetooth earbuds and smart bracelet charging modules.
Wide Input Voltage Range: The input voltage typically spans 2V to 24V, covering common low-voltage power sources like 1.5V alkaline batteries, 3.7V lithium batteries, and 12V lead-acid batteries.
High Output Voltage and Current: The output voltage can be adjusted via a potentiometer from 5V to 28V, with a maximum output current of 2A (actual continuous output is recommended to be kept below 1.5A to prevent overheating).
High Efficiency: Synchronous rectification technology achieves conversion efficiency exceeding 92%, significantly exceedingtraditional linear regulators (e.g., 7805, often below 50% efficiency). This effectively reduces power waste and module heat generation.

MT3608 DATASHEET

Here we provide you with the MT3608 datasheet for your reference.

MT3608 DATASHEET

A common MT3608 module has 4 pins (some simplified versions have 3 pins, omitting the “enable pin”). From left to right, they are:

OUT+: Output voltage positive terminal (connects to load positive, such as the microcontroller’s VCC pin);
IN+: Input voltage positive terminal (connect to power supply positive, e.g., lithium battery positive terminal);
OUT-: Output voltage negative terminal (connects to load negative, e.g., microcontroller GND pin);
IN-: Input voltage negative terminal (connects to power source negative, e.g., lithium battery negative);
(Optional) EN: Enable pin (active high; connects to high to activate module, low to sleep mode; can control module power cycling).

Product Categories

2A booster board (ordinary version)

2A booster board with TYPE-C port

It can use Type-C USB input. You can connect the booster board with a USB charger or a power bank via a mobile phone data cable, and easily get common voltages like 9V, 12V, 15V, 18V, 24V.

2A booster board with MICRO port

It can use Micro USB input. You can connect the booster board with a USB charger or a power bank via a mobile phone data cable, and easily get common voltages like 9V, 12V, 15V, 18V, 24V.

SX1308 DC-DC adjustable booster board 2A

It has an SX1308 chip inside. It features small package, high efficiency, and adjustable output voltage. It integrates a metal-oxide-semiconductor field-effect transistor with extremely low RDS on-resistance of 100mΩ, which can achieve large current output within 2A.

Precautions

1、The input voltage must not exceed the module’s maximum input voltage (typically 24V), otherwise it will burn out the MT3608 chip;
2、 Output current must not exceed 1.5A continuously (the module will activate thermal protection or may be damaged). For high-current loads (e.g., motors, high-power LEDs), install additional heat sinks.
3、 When placing the module near high-power components, ensure proper shielding (to prevent electromagnetic interference affecting output stability).
