No -- in fact, that "Inductor Selection" thing that you quote is pretty specific that the series resistance and core loss matter, as well as the inductance. MANY other softwares out there for making one's own PCB's (which i would NEVER charge anyone to help make their own PCB's, after all, its just the board designs of simple modules so if one ever wants a hand in doing so, lemmi know !!)
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.Zdravím, chtěl bych tento modul použít pro proud kolem 700mA ale nevím který komponent na desce se zahřívá. Kam mám chladič umístit? Předem děkuji za odpověď. VCB48_EBO-xxWR3-N Series DC-DC Converters MORNSUN Launches VCB48_EBO-xxWR3-N Series DC-DC Converters for Medium and High-Power Applications Here is How To Serve Different AdSense Units on Mobile Devices on WordPress With PHP. WordPress Has Function Which Can Be Used In Free Way. MT3608 module can be used in application where voltage requirements are under 28V and current requirements are under 2A. Therefore this module can be used mostly in portable equipments like power banks, portable power supplies etc. Moreover due to its low cost it can also be used in educational projects. 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.
IN+ Here we connect the red wire from the battery (or the power source), this is VCC or VIN (2V - 24V) XI'AN Aerosemi Tech MT3608 technical specifications, attributes, parameters and parts with similar specifications to XI'AN Aerosemi Tech MT3608. 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. By using converters you are providing stable voltage to your circuits with sufficient current which you can use to reliably control motors, in this way you will not have reduced behavior with the batteries voltage drop over time

So i just went to Mouser UK (International Company & this is being used just as an example of how to search for one's own self, use whatever you feel comfy with) So search for the exact or close-enough characteristics of the inductor we need for these projects and I've found 14 results in the list after narrowing it down but only using what info is specifically in that Datasheet snippet above, here's 2 pictures from screenshots from me own desktop to further illustrate how to better search for exactly what you need and asked for, or be in the ball-park for better choice options than without these sort of searching: still use a resistor between the output terminal and the load, but instead of connecting the emitter of the transistor to the output, connect it at the terminal between the coil and the diode. This has the effect that the voltage drop of the diode also helps in getting tot the 0.6V required to turn on the transistor. Depending on load, the forward voltage of the diode is 0.2 V and higher ( https://www.onsemi.com/pub/Collateral/SS39-D.PDF, figure 3)
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? I am planning to use MT3608 schematic for my project to boost the voltage from 3.7V to 5V. I am planning on making a customized PCB with all the requirements that are needed for the project. 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. It all depends on the delay of the enable pin.

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. https://nomadaselectronicos.wordpress.com/2015/05/22/fuentecargador-con-carga-compartida-load-sharing/ The three things that matter the most are the series resistance, the core loss, and the saturation current. If you can get your hands on a datasheet for that inductor, then go looking for inductors available more locally to you (i.e. TDK, MuRata, etc.)
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). You are using IRFP9240. This is not suitable MOSFET for this task. This MOSFET requires higher Vgs than you are providing. You are going to have Vgs around 3.6-4.2V. IRFP9240 requires around 10V to fully open (or at least 5V to be usably open). We work closely with electronics manufacturing companies & individuals to understand & solve the challengesuH is a relatively high value for this circuit. It will run in continuous conduction mode at relatively light output load. 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.
