MT3608 DC-DC Step Up Booster Module 2A Adjustable 2V-24V to 5V-28V

🔧 MT3608 DC-DC Step Up Booster Module | AuscomTech

The MT3608 is a compact adjustable DC-DC step up power module designed to increase a lower DC input voltage to a higher adjustable output voltage.

Using the onboard MT3608 switching regulator and multi-turn potentiometer, it can convert a 2V-24V input to an adjustable 5V-28V output with high efficiency and low ripple.

It is commonly used for Arduino, ESP32, battery-powered projects, portable electronics, LED drivers, and DIY power supply applications where a higher output voltage is required.

⭐ Key Features

• Adjustable boost output – output voltage can be set using the onboard trim potentiometer.
• Wide input range – accepts DC input from 2V to 24V.
• Higher output range – adjustable output from 5V to 28V.
• 2A maximum output – suitable for many embedded and low-power DC boost applications.
• High efficiency design – conversion efficiency up to 96% under suitable conditions.
• Low ripple – output ripple specified at less than 100mV.
• Compact module – small PCB size makes it easy to integrate into projects and enclosures.
• Microcontroller friendly – useful for Arduino, ESP32, sensors, displays, and portable power builds.
