This MT3608 module is a highly compact-sized boost converter with 2A features the MT3608 2 Amp step up (boost) converter, which can take input voltages as low as 2V and step up the output to as high as 28V. The MT3608 features automatic shifting to pulse frequency modulation mode at light loads. It includes the under-voltage lockout, current limiting, and thermal overload protection.
This module has a multi-turn potentiometer that you can use to adjust the output voltage. Since the potentiometer has 25 turns of adjustment you can easily adjust the output of the module to exactly the voltage you need.
Boost converters are a great way to easily increase a given voltage, but that boost comes at the cost of less output current compared to the input current.
Since this is a Boost Converter the output voltage has to be higher than the supplied input voltage. If you need to decrease (step-down) a voltage considers using a buck converter such as our LM2596 buck converter module.
We also offer a 5A boost converter if you need more than the 2A of this module – XL4051 Boost Converter Module.
