2 PCS DC-DC MT3608 Step-up Power Supply Module Adjustable Boost Converter Input 2V-24V to 5V-28V 2A

Product Information

Another thing to mention when working with power modules like converters is that they will burn out if the current goes too high. I believe that you have already understood that from the step above, but how to protect the IC from the high current? Pin configuration of the Step up module is given in the table below. The module has 4 pins, 2 of which are for voltage input and 2 are for regulated output voltage. The module also consists of a potentiometer which can be used to adjust the output voltage levels.

In theory, it should provide 5v (output of the MT3608) when powered either from USB wall charger or from 18650 battery (through the TP4056). The Mosfet will do the switching between mains and battery.Here we would like to introduce another component: the Fuse. In this specific case our converter needs protection from 2 Amps. So we will take a 2 Amp fuse and wire it according to the image below. This will provide the necessary protection for our IC. This tutorial will show how to use the MT3608 boost converter to power up devices requiring different voltages. We will show which are the best types of batteries to use with the converter and how to get more than just one output from the converter.

Here is the TP4056 Datasheet. Here is the MT3608 Datasheet. We are not going in to details of TP4056 (which is a charger circuit) and MT3608 (which is a DC-DC boost converter). The datasheets will give you a fair idea that the end output voltage will be regulated and linear. https://nomadaselectronicos.wordpress.com/2015/05/22/fuentecargador-con-carga-compartida-load-sharing/ Kruh dvaceti čtyř inteligentních NeoPixel diod, u kterých lze jednotlivě nastavit intenzitu červené, modré a zelené barvy. So as per your "Inductor Selection" Snippet you used from the datasheet (AeroSemi?) for the Step down converter MT3608, which tells us the important criteria we need to search with, being an inductor of:I meassured the output voltage and it is stable when the RPi is off as well as when it is on (4.9v ~ 5.1v). The boot up sequence tipically consumes about 150-300mA on a Raspberry Pi B+ I use to prototype. In the MT3608 module, which is available mostly in the outside market, the inductor used is 22uH. Below are the MT3608 module and the Inductor component that is used in the MT3608 module. This is a boost converter meaning that it will take lower voltage and convert it into higher voltage. To adjust the voltage we have to do a couple of steps. Here you can see how the MT3608 module looks like. You can notice that the MT3608 is an IC, and the module is a circuit built around the IC to make it work as an adjustable converter.

uH is a relatively high value for this circuit. It will run in continuous conduction mode at relatively light output load. Because you have moved the current resistor _before_ the voltage regulation network, once the regulator is turned on, the output voltage will be exactly where you want it. Explicitly said: the current regulation network will see a lowered voltage because of your added resistor and will increase the output to compensate for the voltage drop caused by it. That’s its job.

Před prvním použitím je tedy nutné použít vstupní napětí 2Va nastavit požadované výstupní napětí. Potom lze na vstup připojit zamýšlené nižší vstupní napětí. Specifikace: The amount of busted modules ive got over the years ive started to buy the SMD individual parts so i can swap them out as the most important part of the module is the PCB itself. And much harder to make for folks just getting into electronics and electrical engineering :)For any electronics project, we require a power source. In our previous article How to Run an ESP32 on Battery, we have discussed about the challenges with direct powering with battery. As most of the projects require 3.3V 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. Building a DIY power bank with TP4056 and MT3608 is cheap and easy (the matter is about joining the modules). The components you need to build this DIY power bank are : The module is using very less amount of components and the main component of the module is MT3608 IC. MT3608 is a highly efficient voltage booster IC with many built in features like over heat protection, low quiescent current, soft start function, low external components, overheat shutdown etc. 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.

Note that the maximum input voltage should not be greater than the desired output voltage (as this is a step-up converter not a step down converter).

Below is our modified circuit diagram. You can use any of the circuit-diagrams because the result will not hugely differ. It is so easy that ASCII art is enough to draw it. We have added the resistor and LED to Li-Ion cell’s negative to complete it. GND of MT3608 added to GND to complete the circuit. The circuit above depicts how the connections are made for the operation of the MT3608 step-up module. Adjust the trimmer (here 100k Ohm) with a tiny screwdriver until the voltage is set to the desired output. Feel free to turn the trimmer in both directions to get the feeling how to work with it. Sometimes when you use the converter for the first time you will have to rotate the trimmer screw 5-10 full circles to get it working. Play with it until you get the feeling.
