MT3608 DC-DC Adjustable Step-Up (Boost) Converter Module – 2A
The smallest high-efficiency boost converter on the market. Capable of stepping up input voltages as low as 2V up to 28V. Perfect for powering 5V or 12V electronics from a single Lithium-ion battery (3.7V) or USB power.
Product Overview
The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low-power applications. It features automatic switching to pulse frequency modulation (PFM) at light loads. Because of its tiny size and high 1.2MHz switching frequency, it allows for the use of very small capacitors and inductors, making it ideal for compact DIY projects and wearable tech.

[WIRING DIAGRAM FOR MT3608 STEP-UP CONVERTER]
-
VIN+: Input Positive (2V to 24V)
-
VIN-: Input Negative (GND)
-
VOUT+: Output Positive (Up to 28V)
-
VOUT-: Output Negative (GND)
-
Adjustment: Turn the blue potentiometer Counter-Clockwise to increase the output voltage.
(Note: If the voltage doesn’t change, turn the screw 10-20 times counter-clockwise; sometimes they come from the factory set to the maximum).
