MT3608 Step-Up Adjustable DC-DC Switching Boost Converter

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’s efficient

It can source a good amount of current

It’s inexpensive

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).

SPECIFICATION:

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

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.

Note:

1).The input voltage should not exceed the maximum input voltage
