What it does:
Takes a lower DC voltage as input and boosts it to a higher DC voltage.

It's often used when you have a low voltage source (like a single-cell Li-ion battery) and need a higher voltage for something else (e.g., 5V for a microcontroller).

Input and Output:
Input voltage: typically 2V to 24V

Output voltage: up to 28V (adjustable via a small screw potentiometer)

Maximum output current: around 2A, but realistically more like 1.2A continuous due to thermal and efficiency limits

Example:
If you feed in 3.7V (from a Li-ion battery), you can boost it to 5V, 9V, 12V, etc., depending on your adjustment.

1. Dropping voltage is a relatively easy process, but creating a higher voltage out of a lower voltage almost seems like alchemy. The MT3608 uses a clever boost circuit with an inductor to turn a low input voltage into a usable higher output voltage. But as any good alchemist (or engineer) knows, there’s always a cost involved: You may get more voltage, but the trade-off is a little-less than proportional output current. That means if you start with an input that has low voltage and a set current ability, you get high voltage and even lower current on the output.

Specifications:

• The maximum output current: 2 a
• Input voltage: 2 v ~ 24 v
• The maximum output voltage: > 5 v – 28 v
• Efficiency: > 93%
• Mechanical properties:
• Product size: 36 mm * 17 mm * 14 mm

Note: The input voltage should not exceed the maximum input voltage
2).Peak current output current is not more than 2A for input & output.
