USB-PD: 5-20V Power for Your Projects

[@grahamnichols1416]

Great to have Bill back, and sounding back to his normal superhero self.

[@john_hind]

One correction: I believe that the maximum current is 5A so a 20v PSU output is limited to 100W. The latest PD standard also supports 28v, 36v and 48v for up to 240W maximum. Unfortunately while voltages higher than 20 are supported by the latest PSUs they do not yet seem to be available in trigger ICs. There is also an interesting variable voltage profile which is presumably designed to allow compensation for voltage drop over cables, but could be used to make hybrid switching/linear lab PSUs. Set the PD voltage about a volt higher than the desired output and then feed through a linear regulator to trim the voltage down to the desired voltage. Minimum ripple with maximum efficiency!

[@Raze_134]

Your timing could not be better. I was just looking into this exact topic an hour ago for a new project!

[@azyfloof]

A while ago I wanted to build a USB PD Analyser that I could plug chargers into and it would tell me the voltage and current capabilities. I was at a loss where to start, but this video is gonna be a HUGE help! The Adafruit module looks like it's gonna be a great fit, just read all the data over I²C and display it on an OLED screen or something :D

[@justmc62]

Thank you Bill- Another great informative video . Can you elaborate on the large power adapter you are using that has the digital output display ? Looks like a nice unit .

[@lionelreesable]

Hi, what is the make and model of your desktop USB-PD Charger?

[@Hangs4Fun]

This was a "powerful" video, thank you very much :-)

[@donaldkormos5529]

Thanks Bill for a great USB review!!! Cheers ...

[@kahe7436]

I had questions about these power modules for a long time but didn't get an informative one and this one was the one I was waiting for Thank you for such videos ❤

[@Ducerobot]

Every time I think you covered it all you come up with something new .😁👍

[@nathanbanks2354]

Note that 240w is obtained using 48v at 5A (5:05). Older, simpler adapters can't negotiate this much power.

can't wait to be running my 3 phase several hp motors on usb c, at this rate it'll be only 5 years the mains coming from the power lines probably gonna be usb c too

Bill, nice to see you back! 👍

[@zorabixun]

😊 as always it's very interesting to watch your videos, and to learn so much from your knowledge, thx and I am always happy to see your videos , nice explanation, and to watch any your videos present and older ones 🎉

[@akiddoo8113]

Thank you. Cleared up a lot of questions.

[@Lorenzo0077]

thank you, your videos are a pleasure to watch .

[@jrkorman]

Nice intro to the PD part of USB. Thanks. As a protocol, USB is nice. However the physical interfaces are awful; I'm being polite.

[@whitneydesignlabs8738]

Hi Bill, and everyone. In any of your tinkering, did you by chance come across a way to provide 5v at 5a to a Raspberry Pi 5? Thanks for clearing up all this mystery of USB c pd and showing us some cool modules to use in our projects!

[@wizardy6267]

lol, this is a good and useful episode, thank you. Looking forward to the next tutorial

[@winlose3073]

Very nice video Bill thank you very much!

[@bertblankenstein3738]

Very informative as always. Thank you.

[@RoyArmy-WREW918]

Very interesting, but have 1 question ... What is the Model Number and Source / Cost of that "Favorite" USB charger with volt / amp display???

[@wherami]

Yeah he mentions its name nowhere in the website either. I really want that

[@denouch358]

I would like to know also.

Thanks a lot for this video! I had no idea about USB-C/PD but you explained it all very well so now I do. This definately opens the door to new project possibilities. Thanks again

[@steveurquhart5895]

This has been a big help, Thanks😊👍

[@uditfand817]

Thank you for information, great effort

[@km-electronics1]

I rate this video at 240W. 👍

[@codecage9333]

Bill, how about adding a pinned comment providing a model and/or link to you desktop USD-PD charger with the digital display. There is a model listed in another comment but it is only 180W and the USB ports appear to be different versions than can be made out on your charger.

[@janmenzinga]

Hi Bill, how are you doing now and how's your mother doing? Nice video again 😊

[@caffeine347]

great content as always !

Isn't the selectable voltage of the ZY12PDN a little dangerous for devices that can't handle higher voltages?

[@susanguha9]

Is it possible to use any android mobile touch screen display and use it in any diy project.

[@ltan888]

Hi DroneBot, what is the brand and model of the 240W USB PD Charger with the digital display shown in your video? I'd like to purchase one as well.

[@JanDahl]

You forgot about the USB 3.0 SuperSpeed B-connectors.

[@gg-gn3re]

yea that ugly block thing is actually one of the best connectors, impossible to break and can always plugs in well

[@MahBor]

What hapenned to DB1? It needs to return!

[@myITguyShawnRatcliffe]

infact this has spoilt my interest now another time maybe

[@waltermelyon4300]

Is it possible to get negative voltage out of a USB-PD? I have a 1980's microphone amp that required +10v and -10v DC from a 4 pin DIN connector.

[@911canihelpu]

reverse the polarity? :/

[@RobertoColi]

I think yes, if you start with 20v, with some components you can create -10 +10 for the microphone, BUT... I don't think it will be good for a microphone and audio recording. All those powers are coming from a switching power supply that for audio matters are bad and noisy, but you can try.

[@waltermelyon4300]

@@911canihelpu And how would I do that? Once a rectifier strips out a polarity from the AC current how can you change the polarity of the output DC current?

[@jyvben1520]

@@waltermelyon4300 H bridge, as used in reversing polarity for dc motor, but for 10 V from 15/20 you might need to pwm it, does it really need 10V would 9V be enough ? capacitors on all dc power lines might help make it more stable, 10V might be to compensate for powerloss from wire resistance, long wires to/from amplifier

[@PainterVierax]

​@@waltermelyon4300 You need the ground not in a floating state (meaning the mic amp can be plugged on any other grounded device) so you might need to use a transformer somewhere to get that negative voltage with enough amperage capability. As roberto said, your amp probably requires a very clean power supply though so you might have to forget about using any SMPS and get a good old linear PSU instead.

[@JanDahl]

The U in USB is for nUts

[@AW-tc4hy]

Pd is stupid complicated. Any pwm charger can have variable voltage by simply changing the resistance of the feedback voltage.

your title is worded more like an ADVERT than a content vid. I normally just click do not recommend for such videos. Lucky this time i check but bare it in mind cus that is my normal ploy

[@Manuqtix.Manuqtix]

How are you doing, how is your mother??

[@RobertoColi]

Very nice and instructive video. But I see now around 2400 views and only 400 Like! 😦 Come on boys, if you like the content of the channel, don't forget to to click on like. Do it during the video! I have some devices (e.g. Firestick) where, when the video is over, you can't click like any more, unless you start the video again, and get all the ad again ;) (...and sometime is even tricky, because KZbin may hide the video, since you have already seen it)

[@alancalvitti]

dude u want to pause a sec or 2 when u throw up a graphic?

[@randallstephens1680]

"5-20V power" doesn't actually make any sense. Voltage is a measure of electrical pressure, not power.

[@michaels3003]

Electric potential. Pressure was used with steam machines.

[@gassanali8667]

First

[@AW-tc4hy]

Hahaha pd is unnecessarily complicated and expensive. In pwm chargers, switching to different resistance in the sensing would change voltages, being that simple for so long. Another rubbish scheme to expensive hardware. No wonder EU support it strongly. Must be kickbacks again
