The MT3608 DC-DC Adjustable Step-up Booster Power Supply Module With Micro USB is a low-cost module that can step-up a 2 to 24V input voltage up to a 5 to 28V output at up to 2A.
DC-DC boost converters step up the input voltage to a higher voltage while also stepping down the available current since the module can’t output more power than its inputs.
This boost converter is adjustable and capable of outputting a voltage in the range of 5.0 to 28V at a continuous current of up to 2A depending on input/output voltage settings with 1A available with most settings.
Since it is a boost converter, the input voltage must be lower than the output voltage.
The device is able to use low ESR bulk ceramic capacitors rather than electrolytic caps which avoids long-term aging concerns and contributes to the compact packaging.
The MT3608 converter IC has over-current and thermal limiting features built-in to safely shut the device down if driven too hard.
