DC-DC 2A Adjustable Boost Power Supply Converter Step Up Module 2-24v – Attach it to your input voltage, and twiddle the trim pot until you get the output voltage you need (but it has to greater than the input). There’s also step-down (with display), full-range (step up and down) DC-DC converters with different prices and size factors, but by limiting to one function, you save space and cost.
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. Keep this in mind, and you’ll be fine!
To summarize, the positives are:
It can source a good amount of current
It’s simple to adjust to get your desired increase in voltage.
The negatives are:
Your selected voltage output HAS to be higher than the input
It creates the voltage with an inductor, which by its nature creates a bit of noise on the power line
It can only work within the limits of physics, which means the power out (volts*amps) of it will always be lower than the power going in (volts*amps).
The maximum output current: 2 a
Input voltage: 2 v ~ 24 v
The maximum output voltage: > 5 v – 28 v
Efficiency: > 93%
Product size: 36 mm * 17 mm * 14 mm
Connect the IN+ and IN- of the module with 2~24v
Adjust the potentiometer to adjust the output voltage. Please be noted that the output voltage should be higher than the input voltage.
1).The input voltage should not exceed the maximum input voltage
2).Peak current output current is not more than 2A for input & output.
