I know what you're asking, basically are there any equivalents or alternatives to the inductor choices that fall within the criteria of the datasheet and where i do humbly think, personally, that this info will further benefit ANYONE/as many as possible when they also read this answer, so not only for the original question post's author, but i surely hope everyone too, here goes: 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.

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.

XI'AN Aerosemi Tech MT3608 technical specifications, attributes, parameters and parts with similar specifications to XI'AN Aerosemi Tech MT3608. 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. S8050 is an NPN, a general-purpose transistor. This article mainly covers datasheet, pinout, equivalents, applications, and other details about S8050. Read More

Took me a WHILE to get this all down as I'm dyslexic so please do expect a few mistakes here & there by me, lol, but i hope this helps with component selection going forwards from specific data laid out in the manufacturer's datasheets to have a lot more options available to those whom love making their own PCB's 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. 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 :

IRF2807 Transistor, Its pinouts, Features, Equivalents, Applications and Other Useful Info October 26, 2023 Nice touch, a limitation: as mentioned, it introduces a voltage drop of 0.65 V (or so). This voltage drop is current dependent, so you can’t really regulate this away easily using the variable resistor. The resistor needs to drop at least 0.6V in the “converter-off” situation. So, if, like in the example, you have 4V input and 15V out, and the load is resistive like the lamp, then you’ll be dropping about 2.3V across the resistor when the thing is on. 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.

Trimry bývají občas z výroby nastavené úplně mimo oblast, kde je regulováno výstupní napětí. Pokud nefunguje regulace výstupního napětí, zkuste otočit trimrem 25x na jednu stranu, případně poté 50x na druhou.

uH is a relatively high value for this circuit. It will run in continuous conduction mode at relatively light output load. 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.) Set the multimeter to read the voltage and connect the output of the converter to it. Now you can already see the voltage on the output. A boost converter(DC-DC step-up converter) is used to step up a lower voltage to a higher voltage level with quite a simple circuitry. It is a type of switch-mode power supply as it uses a switching device to regulate the voltage. In our case, the switching module is the MT3608 IC which has a high switching frequency of 1.2MHz. The higher switching frequency also opens up the possibilities to use smaller indicators making the module compact and also providing high power output simultaneously.

But for a resistive load will it go into runaway trying to regulate the voltage since the current will keep increasing as the voltage increases? 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 RP2040 and ESP32 are all microcontrollers. This article is going to talk about the differences between them. Read More 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. Boost converters are a great way to easily increase a given voltage, but that boost comes at the cost of less output current compared to input current. Since this is a boost converter the output voltage has to be higher than the supplied input voltage.
