    🔥I always use a 3.7V battery charger module and then I add a boost converter to get the 5V for my Arduino and so on. I wanted to have everything on the same PCB so I've used the protection ICs, charging and boost ICs and like that I have all I want on the same PCB. Hope you like it.

    12:04 To fix this issue just connect the 20K resistor permanently to the circuit. Then, just calculate which resistor value you need to put in parallel to that to make 7K, and just make the switch connect it in parallel. That way, you can either have 20K or 20K in parallel with whatever is connected to the switch. This means you'll never have a floating pin.

      A different solution would be switching the resistor to ground. In that way the ic will stop working while floating and turn on when the switch is closed again. Second feature is a damaged switch shut the ic down.

    Nice project man, you did a great job with this module.
    BTW for the switching problem I don't know if someone has mentioned it or not but if you take a look into the Vout equation you can see that when you disconnect the resistor R1 for a very short time this makes its value approaching infinity and according to the equation the boost converter will try to reach a very large voltage value that will destroy the ic
    I think the solution is to make R1 constant and change R2 according to the desired output voltage, this will make the switching moment voltage equals to Vref

    Great content, and a nice detailed explanation of the design process 👏. May suggest in theory that the booster short circuit could be fixed by a mosfet/pjt of the same rated current, as such, if the 5-12V switch at bounce state, the gate(mosfet) or base won't be supplied thus short circuit; you can ensure the drainage by a load resistance. Another way can be a capacitor put across the booster output so it doesn't lose current instantaneously at the switching action, however, this may be not the safest option to turn off in safe fail mode.

    Hey Electronoobs, loving your video and concept for a charger/boost converter. I've recently made my own usb charger boost circuit and found that another IC made by TP to be even more suitable. The TP5400 comes as an all in one IC that can handle charge, boost, protect, and has internal mosfets. Might be worth taking a look at that IC. However, the only downside is that the datasheet is in Chinese only.

    By the way, to make the board even smaller you could use a battery protection IC with integrated mosfet instead of the DW01. Check out this one: XB3303A. It's available in LCSC.

  • @mundo_electronica
    @mundo_electronica 4 ปีที่แล้ว +22

    Hi. It's a great idea, but I suggest two things to improve the circuit. First, use a FS312 instead of the DW01, because this chip have a 2.9V under voltage protection, instead of 2.5V, it's more safer for the Li-Po than the DW01. Second, use the switch to conmutate the R2 value, not the R1, in this configuration the FB pin always see the voltage of the output, and if the R2 value is floating, the voltage in the output will be 0.6V, the feedback reference voltage, and the IC is safe 👌🏻(Perdón si mi inglés no es muy bueno, pero prefiero comentar en inglés en tu canal de habla inglesa).

  • @Nono-hk3is
    @Nono-hk3is 4 ปีที่แล้ว +4

    Also, be aware of the current rating on the surface mount switches. Good engineering design calls for at least 2x margin, i.e. if the battery can sustain ~500 mA the switch needs to handle *at least* 1000 mA. (This margin should be much higher than 2x if we were dealing with higher power.)
    One solution is to use an N-channel mosfet to switch ground back to the battery. Then attach the smd switch to the gate to turn the mosfet on and off. But when it comes to things like power supply, I don't like low-side switching as it leaves the load energized, so if it finds a ground it might turn itself on.
    So if you can find a p-channel mosfet that handles the required current and can be saturated at zero volts (rather than having to go negative) you can switch the high side of the battery instead. So look for a P-channel mosfet whose Vgs(th) is only about half of the voltage you want to switch. This increases the likelihood of the mosfet going into saturation.

    Eg. If I put a 4.2V or 3.7V lipo to charge? Is there something I need to change for this?
    By changing the inductor to a larger value would this mean that I can charge at a higher rate?

  • @dominikworkshop6007

    Cool board, but i guess i have a better solution to your problem. I suggest connecting the 20k ohm resistor (R1) permanently to the voltage divider so you would have 12V output and connect another resistor through a switch in parallel to the 20k resistor to obtain 5 volts output. This way the boost IC will always have its feedback loop closed.

    Hello, I already had a problem using the DW01, he just couldn't keep the output off permanently. It restarted whenever the cut-off voltage increased, as the battery stabilized. It was necessary to trick it with 2 diodes in series for voltage drop and also an electrolytic capacitor to prevent reclosing. The shear stress of the FS312 seems more stable to me, test it if possible!

    whats the total cost: if I was to order the V2 board 5 count assembled. it's hard to know the actual cost per board (fully assembled) without the required files ( before purchasing them) thanks

    To solve your problem with boost ic, you can just add new two resistors in range 300k to 600k in Parallel to your old resistors and switch, so in normal operation the small value"old resistors" will take the controller and set the correct output, and when switch flipped the new resistors will kick in and set the output voltage to 5 voltage until switch flipped, after that the olde resistors will kick in and set the output voltage to 5V or 12V.

    Dear Electronoobs,
    for the sake of the clearity i'd highly recommend cleaning PCBs with acetone before shooting. It makes them look much more professional.

    Great video and PCB! Just wondering - instead of adding a second switch why not just use 8.5K for R9 and then use a single switch to short out a 12.5K resistor? That way there is never an open circuit in the voltage selector.

    I have a question, what happens if you have the power supply (micro usb) connected and you have a loud at the end. Will the LiPo Cell charge or discharge? And will the load get current or not if i do it that way?
    Nice video keep on going pal. :)

    You mentioned that the PCB is populated one sided because of future need to order them preassembled from JLCPCB ? How much would this PCB cost assembled with all the components ? I suppose you could also do hot air reflow soldering at home instead of soldering each SMD component by hand.

    The booster IC blew because it had no voltage feedback and went overvoltage on the output.
    As you flick the switch the IC momentarily loses voltage feedback and thus thinks that the voltage is too low and during that time the voltage rises to a level where the IC burns out.
    So it's just a bad design on your part. :)
    To fix this you could have left R1 permanently connected and had the switch connect a 12.3 Ohm resistor in parallel, which would lower the total resistance to 7.5k.
    Or you could flip the thing around and place two resistors instead of R6 and one resistor instead of R8 and R1.
    This way the regulator would jump down to 2.5V during the time it takes for the switch to make contact. This would also be the ideal way to do this because it would mean that in the event that the switch failed your regulator would not go overvoltage and burn out everything on the circuit.
    Also your boost output capacitor should be placed as close as possible to the diode to minimize voltage ripple at higher current.

    Can you tell me the exact version of the dw01 using ??? Because you are using dw01a (acc to schematic) which has an auto-recovery feature then you are able to achieve that during over-discharge, only USB input will enable the system.

  • @fjcchfer

    Excelente placa, yo diseñé algo con el tp4056 y el dw, pero no logré que funcionara, siempre se cortaba jajajaja, tuve que deshabilitar la parte del DW, por otro lado se me haría interesante que tuviera 2 salidas independientes, una para 3.3v (o 5v) y una para 7.5v ( para manejar pequeños motores), crees que haya problema si modifico tu diseño para que de una sola celda, tomen energía 2 sistemas BOST?

    So i made battery back 7s configuration. To be charger PD charger but it can only charge at 20V. My battery input output supports up to 30V charge. So i need to make boost converter that can turn my 20V to 30. Also disconnect it self from battery when battery is full. So that i can get max 30V out from the type c when i remove charger. It also needs to disconnect 30v from battery to type c, when ever charging is started.

    Although I am a bit late to this, this is exactly what I'm looking for, I don't need the 12v so how would one remove it from the schematic?

  • @helmuthschultes9243
    @helmuthschultes9243 3 ปีที่แล้ว

    Better solution for voltage select is to switch the resistor value by bridging one resistor in one state and connect both in series in the other mode.
    Means for example 7.5k in series with 12.5k for the 20k in 12v, with the 12.5k bridged by the switch for 5v, so 7.5k in 5v mode and 20k with 12.5k connected/not bridged for in 12v mode. At no time is the feedback disconnected and it becomes safe to switch even with battery in place.

    I found a similar module with a 9V/12V switch. The switch would break before make, so the boost IC burned when I switched the output voltage while powered, just like yours.
    Maybe you should consider a make before break switch, or a different resistor configuration as suggested in another post.
    A make before break switch would have avoided the problem.

    @atinotevuelveaimportar5905 4 ปีที่แล้ว +2

    Better than a switch I think a jumper that you can just solder will be more useful to select the 12V: then the freed space you may use it to include a M2 hole in the pcb for fixing ir in the project case.

    Hello. Looking to use your design. It’s perfect for my use.
    Looking for advice of changing a few things
    For a 2s configuration. 7.2-8.4v
    Would have to use 9v/12v boost
    What would need to be changed on the charge protection
    Different chip/resistor value changes?
    Boost converter portions.
    Same chip for 24v
    Do I change the resistors for the higher voltage coming in.
    Any help on values and portions would be appreciated!
    Finally got a 3d printer to do more of your projects.

  • @zstergios

    Amazed!
    Consider adding power path, when battery is fully charged.
    Consider adding switch to turn off leds (for iot usage).
    Consider adding adjustable charging current for Dual Battery (2P 28650)
    I am searching a module with features above. I want to build a remote sensor with esp32+gsm (nb iot)+2P 18650+ solar panel (v6 to v12).
    Any recommendations?!!??😅
