I get excited in every single video he uploads! This channel is definitely black magic! Thank you!

This is awesome. I would love to see a video involving the opposite process of taking DC power and making a usb - C source device.

This was much much needed, thank you again for making such great content!!

These design videos are my favourite. Thank you, Phil.

Thanks Phil, another great video, looking forward to the next part. And this video reminds us the internet stays up each night in anticipation of your imminent video on ESD and power filtering!

Your channel is a diamond mine of information. Thank you!

These videos are a breeze to watch even as an electronic noob. Thank you!

Thank you. Would love to see a video like this but additionally with lipo battery+charging.

I've spent the last few months trying to learn about how usb pd works, I tried studying datasheets and reference manuals but i only became more confused. Thanks for making this video it really helped me a lot 🙏❤

This is great and complete. Thank you.

Truly one of the best sources for professional electronics engineering on the net. Thank-you. I'd love to see a similar video but using bidirectional source/sink of 100W, and also 240W. ICs for src/sink seem less available - TI has TPS25750 that I've been looking at for a 1S2P battery operated device.

Great walk through of the process 👍

Hey Phil. Did you upload the follow up video regarding i2c communication with the st board?

thank you for the knowledge sharing, sir!

It would be interesting to watch something about POE in a next video (like a power supply series). There must be many interesting things like POE classes, Ethernet transformers, MOSFET as diodes, power controllers, ets.. It could be a POE "injector" that adds POE capability to any Ethernet connection. Network drives, media centers, IP cameras, etc... these are possible consumers which likes POE

Exactly what I've been looking for! Thanks man!

Phil, nice design, as always, and lots of attention to details. Thumbs up for your work! About a year ago I've designed USB-PD sink device, using STUSB1602 with STM32 uC. For some price-sensitive designs it's enough to use USB-PD triggers, such as WCH CH236. Docs are not as good as Cypress, TI, ST and other monsters, but it works too.

Yay it’s online, can’t wait to watch it 🎉

What a great video. thank you. I am trying to build a 6 port usbc PD hub from household AC current. I was going to use a step down transformer to generate the 12v needed but wondering if this is a better approach. I dont need data, just power

Fantastic content. thank you

Thanks for the video! Your channel is amazing.

This is so amazing 🎉, I really enjoyed working this, but please do you have a video on firmware for stm32 talking to pd controller ?

It would be awesome if you could make a video on wireless charging, particularly the type that are used in electric toothbrushes. There is scant resources out there, and it seems like a handy circuit for a lot of rechargeable applications.

Thats very interesting! And just what I wanted to research next anyways. Thanks!

I have been trying to work out what the VDDD and VCCD lines are for, which wasn't really explained. According to the datasheet (Page 5), the VDDD line is a 3.3V output that can be used for the VBUS_MIN, VBUS_MAX, ISNK_CRS and ISNK_FIN lines, so I'm guessing these lines don't necessarily need an external 3.3v buck converter like you have. Funny enough, Page 4 also says an external source of 2.7 V-5.5 V can be used to *power* the IC on VDDD line if nothing is being supplied to VBUS_IN. Still trying to work out VCCD, which also seems to be a 1.8v output. The only reference I could find for this line was "Output voltage for core Logic", but just goes to ground anyways?

I just love this stuff

Excellent video. You should consider getting a camera and tripod for doing the demos.

Nice info, keep it up, thanks :)

I would love to be able to download this design and play with it. I don't see any links to it in the description. Great video truly!!

this is serious level explanation lucid with plain clear english and structure totally different from your daily ,,dosto`` videos ps the 4.7uF at the jack is a bit dangerous a bleeder should be there if your last device was 15 v and the next one you hook there is 3.3 things might go bad

Very nice video Phil. Cheers. Also, are you still working on another course and if yes when will it be available?

Very timely for me! I have nothing to add except there are only two kinds of slashes. Slash and back-slash. Linux like slashes. Microsoft likes back-slashes.

Hello Philip I'm still patiently waiting for the promised can bus application video. I'm very curious to see how a professional would do it. Cheers 😊

Great video, Phil! Have you managed to communicate with the PD controller via I2C? I don't see any details, nor the registers description in the datasheet. Have you found any?

Hi, Chapeau for your eloquent and very clear presentation. Would the Altium .PrjPcb from this design be available. I looked everywhere. I also looked for the CY4533 data @ Infineon, hardly useful. I have Altium, so I can adapt the board to my mechanical requirements. Thanks in advance.

Hello, I enjoyed the video. Is it possible to do it the other way? I have a DC barrel type adapter and I want to change the connector part to PD type.

Thank you. for the SMD Cap sizes What are your Rules? Whats the size of Bigger Caps?

I was reading many datasheets for the pd controller and your video class helped me a lot, It would be more helpful if you could show how to do the pcb design, Any way I wanted to connect output to piezo speaker KEMO L010 speaker. Thank you.

Great videos Phil, love watching them! My question is, is there a possibility of connecting output of DACs to Vbus MIN/MAX and ISNK COUSE/FINE pins in order to have it controlled via MCU (connected to D+ and D- like you did in this board)? And if so, would it have some strict limitations in a sense not to exceed power limits (and possibly damage device) from the USB-C connector? Thanks for making these videos, very much helpful!

Your tutorials are incredible and they make electronic so easy. A slight clarification. If USB-PD IC is configured to get 3A at 15V (45W), is it possible to get a current above 5A at a lower voltage. (Eg: 6A at 7.5V) by sending through DC DC buck converter? Power losses are ignored.

Saw some comments on how to basically reverse this video. That is, make a usb c power hub. That is what I am really interested in. I do not understand how before the hardware closed the bidirectional Power Switch/ Bus it negotiates that the voltages are correct on the other side. This would be great video for designing a usb c power hub.

Why did you end up using a buck converter? If I’m understanding correctly pin 23 already provides 3.3 v

If it comes to simplicity, just use a CH224K. Costs much less than the CYPD3177 and has only 3 gpios ehich can be controled by a micro or jumpers

Thank you Phil for the Video. Looking forward to every one of them. I just have one question When I want to charge a LiPo Battery with USB C say with 1A at 5V with a lipo charger IC. Can I just work with the Resistors on the CC-Lines? Or do I also need an IC to request the Power, because there could be a Power Supply, which doesn't deliver enough Power. Or is it safe to just use 1A at 5V. Thank you

Please also do a PD 3.1 Board with 140 or 240W!

Thanks for the video! It would be awesome to see some hardware design powered with POE. Did you ever designed something like that?

This is all fine and dandy, and yes you can get these boards for pennies on the site that shall not be named but I'm more interested in the reverse.. a board that contains a buck converter, an appropriate mcu and PD chip that can set the buck converter to supply the asked voltage. IE.. supply it with 12V from a generic source, then transform and regulate that voltage to what is asked on the PD port end of things. Why? for one, it would be a nice thing to have to convert existing fixed voltage PSU's to something more versatile , also it would be nice to have a cheap device that can supply the non spec 5V5A a PI5 asks for from standard 25watt delivered through a spec compliant PD supply. I've been on digikey but unlike with the IC's described in the video the ones doing the reverse , while i'm sure they exist, are somewhat elusive (to me) i'm probably not using the correct search terms. Any info from frankly anyone would be nice. Cheers.

Did you make that follow up video with I2C comm to the PD controller? It seems to me that a lot of these PD controllers don't detail the I2C communication for host MCU, hoping this one stands out.

Please do something on the pd source also. There are not many resources on designing usb pd source.

Hey, very interesting Video. Do you perhaps also planning a Video how to design a POE „Client“ , like a POE HAT for a Raspberry, or such like this (or a POE to USB-PD converter,…) 👍

I didn't know USB-C can deliver 100W. That's amazing

Hi, I couldn't find any playlists about KiCad for beginners, do you have any videos on that? Thanks!

Can you publish the schematic of this board ? either in pdf or in altium file would be very helpful!!! i am intersted in the vconn connection , should it be connected or not ? is it mandatory ? What is hte purpose of the R18 20k PD resistor , it seems none mandatory you can drive the mosfet directly no ?

Hi, can you maybe provide what USB-C power supply you are using? I have 5 chargers at home And I am not able to negotiate 15V@3A with any of them. 20V is working fine.

Hello sir, I need to know, The USB PD chip canbe used without microcontroller. And Its also have its own 3.3V integrated voltage regulator so why we can not use this 3.3V supply to the ISNK and VBUS voltage divider resistor.

Great video as allways! Here are a few questions/notes: 1 isn't the input capacitance to much for the USB standard? yes they will be derated but still 2 Why you didn't use a LDO ? asking since this setup will use so little current the area for the buck may not be worth it economically + that inductor is so large you could even fit a large Dpack LDO in there for probably less cost 3 you said you had a few STM32 s around, did you hand assemble the board or was a PCBA ed? 4 IF a voltage is not supported like lets say 15V will this error out and got to 5V ? 5 IF there are 2 available voltages in your range will it go for the lower one or the higher one? 6 Why did you go with a common source Pmos and not a common Drain ? ( also same question for cases where a configuration is not explicitly said in the datasheet) 7 Is there a standard pin out for that connector you showcased?

11:19 can i use ATMEGA 328 P instead of STM 32

What's the longest cable you can use for USBC PD, for 100W or 240W?

Interesting. I've noticed that on USB3.x that just connecting the SS USB pairs is enough to get full USB3 up. No USB2 needed!

Does anyone know if there are any solutions out there for e.g. adding a USB-C PD port to an existing DC power supply? I have one made from an ATX computer power supply, and I'd love to be able to access something like 100W via USB-C PD, supplied by the ATX supply. I'm using one of those Chinese boards which take the ATX connector input and break it out to individual positive/GND for each voltage (3.3, 5, 9, 12, -12). I've been looking for a way to use e.g. the 12V output as a power source for a USB-C port providing PD, but it seems that all the resources online are for the opposite (as in, making simple 'adjustable' power supplies by using a USB-C wall adapter and one of those PD "trigger" boards). What I want to do is more like if you imagined the demo board from this video, but with a DC barrel jack for the input and a USB-C female connector for the output. I'm actually surprised the usual Chinese sources don't seem to be supplying anything like this. I'm sure it could be done with some effort if I butchered an existing PD wall adapter and inserted the DC input in place of the AC circuitry and rectifier, but I'd much prefer a proper solution without any hidden surprises. There's also the fact that the wall adapter components would be configuring voltage/current limits for the PD negotiations, so I wouldn't get 100W from a 65W adapter (plus, there's the risk that the components used aren't rated for 100W).

Can i put power to dc jack and usb c to out put power ? This circuit can use bidirectional?

I use the Tag Connect headers on some boards, the only thing I don't like about their cables is that they internally connect pins in the connector for some of their cables so they are not generic. I.e. the 6 pin ATMEL IIC cable cannot be used for J-link, so you have to buy two cables that are exactly the same except for the internal shorting. They are a great design though, and really speed up programming multiple boards. I have a little power injection board between my ICE and the target board, so I can also power it as I program if needed. The ATMEL ICE by itself does not source power.

Can anyone please explain to me why Q1B is needed? i am very confused. if we have the the gate at logic low and Q1A conducts but wont Q1B then act as a deterrent for current as the esd diode wont let it conduct the other way. please help and can this be used to charge a battery for example connected where the Barrel jack is.

Thanks for the nice video. Just recently did a design using an OrangePi zero2 that powers from USB-C. Fortunately they have a +5V input header pin. My only complaint is they are making this stuff too dam small these days, soon we will all need a wire bonder to build our prototypes.

The Tag connect header is interesting but not small at all. Once a connecto is smaller then a USB C connecter then maybe it is small

Phil, thanks this video very usefull!. Im also designed my own usb-pd based project and use video to verify my design before manufacturing. One important note about your design: you have 2x4.7uF( one in schematic near connector and another one near mosfet) input capacitance and i not sure if it meets usb-c spec because spec limits maximum inrush current by setting upper limit to input capacitance of 10uF to limit maximum inrush current, given the capacitor capacitance can be x2 times the rated one, you design may or may not exceed this limit set by usb-c spec. Also if you look at datasheet of usb-pd ic its input capacitance 3.3+1 uF which is even given twice the capacitance would likely exceed 10uF actual capacitance. Please correct me if im wrong

How can I just create a usb 3.0 usb-c without PD just Data Communication?

Any type c solution for charging 24V batteries?

why do thin cables cause the voltage drop?

24:18 Question for the Tag-Connect Header: Why does it have 4 larger holes around the perimeter of the footprint? As far as I could see they are not needed for the Tag-Connect itself?

Have you considered using STM32G0 or G4 with integrated USB PD PHY instead of dedicated chip?

I am curious, do your boards work the first time every time ? For example, your very first FPGA board you designed, did it work on the first try ? Just curious to know

Hi Phil, I think you have the answer to a lot of people's problems. What I mean is that new laptops come with USB C charging and more than often the USB C connector gets bent or breaks but the connector cannnot be swapped because the charger then defaults to 5 volts as there is no PD Negoation. As a result, a fair new charger brick is wasted and new one has to be purchased wich contributes to electrical waste etc. The solution to this problem would be try to make a device like in this video that allows you to add a new connector but also does the PD Negotiation with the charger it does supply the voltage the laptop or device negotiates. Can this little board do this? or is there something you can make that allows this? For example, When I cut off my USB C connector on a Dell Charger, I have 3 wires Blue, White and Black but when I added a new connector I cant get it to go above 5volts. Would you be interested in solving this problem and maybe even creating a mini board for sale? You can scan the forums and this is a huge issue across the globe with USB C connectors

Can you help explain why my S23 Ultra which is said has USB3.2 and it fast charges depending on charger so has USB PD capability. why is it not giving an external nvme enclosure that draws between 5W to 10W the power it needs. Does the NVME enclosure need to have PD built in? but since it isn't working... why is it working on windows and not complain about the nvme drive drawing high power? Certainly everybody must be having problems with external nvme enclosures with new nvme drives not getting enough power to it?

most of this goes above my head, but i'm wondering if you can put a micro-usb power output as well? Or is there a better way to convert usb-c to micro-usb-a?

Can I use a laptop usb C PD port to act as a source? Ex: power a 12v device from a laptop usb c pd port?

Q: who needs a stinking #license to Phil in?

Can you make battery charge pcb?😅😅

Greetings to engineer Furkan Kara.

When you are going to publish your High Speed Design Course?

Too bad there are no ICs that support 240W yet. That would bring completely new possibilities. Especially in e-mobility. How cool would it be if you could charge your e-scooter directly with 48V with USBC? 😅

No banana for scale?

The last part of this video would have been a perfect excuse to pull out a thermal camera.

👍🙏❤

We are waiting for video of 100k subscribers and its gift

I like your videos but , could you not boooooooooom so much. My neighbors really appreciate it. :P
