This is then used to switch a transistor, which then connects the enable pin to the positive rail, switching the converter on, leading to the full boosted output voltage being reached. The circuit may need an extra capacitor between the base of the transistor to earth to counter any high frequencies that originate from the switching.

Therefore this module can be used mostly in portable equipments like power banks, portable power supplies etc. Because I’m super dilligent, the video link at the top of the article starts at t=101 seconds, skipping the preroll ad. Fotografie výrobků jsou pouze ilustracemi na ukázku a někdy se mohou lišit od skutečného vzhledu předmětu. If you’re a little hazy on the background, fear not — we’ve discussed the nature of boost converters before. And of you live in a rural location with almost unusably slow broadband, you do not want to go starting videos.The MT3608 is a constant frequency, 6-pin SOT23 current mode step-up converter intended for small, low power applications.

The enable pin of the boost converter is held low through a pull-down resistor, keeping the boost converter switched off. Since the trimpot has 25 turns of adjustment you can easily adjust the output of the module to exactly the voltage you need. As title describes MT3608 is a small voltage booster module that can be used where its requirement to boost voltage as low as 2V DC to 28V DC.Using MT3608 module is very simple by looking at the pinout described in the image above you can connect an input voltage from 2V to 24V DC.

Note: More technical information can be found in the MT3608 Datasheet linked at the bottom of this page. DC to 5V DC, we need some system which can be charged with a mobile charger and the output voltage can be adjusted for different configurations of the power supply plans.Other components used in this module are two ceramic capacitors, one variable resistor, one resistor and one schottky diod and a 22uH inductor which is an important part of all voltage booster circuits. OK, just for the record: We add 10Ω to the *regulated* output of a *voltage regulator*, which was designed to make a source look like a *voltage source* giving the *same voltage* regardless of current draw over a full range? I suppose if you wanted it “off” you’d add a switch to the input, rather than power it down, but I wonder how many applications would idle at the input voltage (minus the schottky diode drop), but require a higher voltage to run? Chances are that an inductor in the same package with the same value will work, but you really want to double check the specifications.
