The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications. The MT3608 switches at 1.2MHz and allows the use of tiny, low cost capacitors and inductors 2mm or less in height.
Internal soft-start results in small inrush current and extends battery life. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. The MT3608 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload.

Technical Parameters:
• 2V to 24V Input Voltage
• Up to 28V Output Voltage
• Maximum output current: 2A
• Integrated 80m Ohm Power MOSFET
• 1.2MHz Fixed Switching Frequency
• Internal 4A Switch Current Limit
• Adjustable Output Voltage
• Internal Compensation
• Automatic Pulse Frequency Modulation Mode at Light Loads
• up to 97% Efficiency
• Product size: 32 mm x 18 mm x 10 mm

Method of operation:
Connect to a MicroUSB power adapter or input 2~24v into IN+ and IN- pads, the potentiometer can adjust output voltage, output voltage is greater than the input voltage up to 28V. Once set the output voltage is a fixed constant irrespective of the input voltage.

Important:
• input voltage should not exceed the maximum 24V limit
• peak current output current is no more than 2A
• please observe the correct polarities as marked by the pads.
