The sheets are important, never the presenter. So wrong balance in camera beamer switching.

Here from Phil’s lab

Folks interested in this should also seek out the RHOM buck converter application note PDF that’s very useful.

Good Presentation but make sure Presentation always in bigger window and presenter in small window. Otherwise we have to pause many times to zoom and check. People will be interseted in Presentation not presenter.

wow, excellent talk

for the people who edit these things: Just display the slides full screen. The info there is relevant, seeing the talking head is NOT. Especially when there are schematics (or anything besides text) you I'd prefer just seeing the slide.

Great presentation and explanation from a PCB Designer prospective.

Where are the white papers?

Alhamdulilah, Your Video Is Very Beautiful, Thanks You Very Much

PCB switching power supplies

This video was recommended to me by Phil. Absolutely brilliant seminar.

Thanks sirr 🙏🙏💯

Very interesting video about rf pcb design ...where can i find slides?

does anyone have the ppt?

It' s a really really good and clear video for power topologies and their layout. Thank's a lot to speaker.

So many traps in this video. Explain how you determined linear regulators are only 60% efficient for any circumstance (Hint, you can't). Also, perhaps research your topic a bit more, as you find that many switching regulators are just linear regulators with an additional controller. Also does not talk about disadvantages of Switch Mode Power Supplies (what SMPS stands for that you happened to leave out). For example, at low load currents, SMPS is nominally worse than linear. Likewise, when input and output voltage are close, linear regulator performs better in effiency, introduces no AC noise, less complex (less supplemental components), and is probably cheaper. Horrible talk on SMPS and linear regulators. Not even sure if your PCB design is good, as im not going to watch it seeing as though you did no research for the beginning of your presentation.

apollo guidance computer used a relatively simple PWM based switching supply as welll

hes kinda hot

9:46 - "Linear regulators are typically 60% efficiency". Ok, that sentence did not really help, as it would be hugely different depending on the ratio of input and output voltages.

Excellent, thank you! Layout examples were particularly helpful 👍

Great lecture

Awesome talk on switching power supplies! Perfect introduction to SMPS circuitry and design considerations.

Would really like to drink a beer with this guy! Nice vid!

The audience seems a little lost...wonder if they were expecting this kind of detail....an excellent presentation btw.

This program have a tool for change outline of component package?

I had this video bookmarked 5 years ago or something. Very few comments. This video is still monumental in pcb design.

at 37:00 i recognize that filter footprint ;) murata bnx02x www.murata.com/en-global/products/productdetail?partno=BNX022-01%23

for the layout example at 28:10 i would not have extended the vout copper pour under the inductor to minimize capacitive coupling from the switch node to the output, one could possibly even have a ground sliver under the inductor to further reduce the coupling, also be aware of inductor polarity for multilayer inductors, you would want the start of the winding (inside) towards the switch node

Fantastic presentation! Thanks

Thank you!

At 31:09 gate drive layout is shown. Having two paths from driver common pin to transistor source, will it form a ground loop? Moreover, ground plane is much wider, so current should follow this path, not a dedicated Kelvin trace. Or, maybe, I get something wrong?

Hi, where are the other videos in this series? I looked at the Optimum Design Associates CZcams landing page and it doesn't even show this video there, let alone any parts previous or after this video.

Obsolescence is slowly becoming a second root cause, especially with electronic parts

Great overview. This is the next level of informative video. Thanks.

Absolutely brilliant and very experienced guy to listen to. Good presentation skills, too. Thanks for this Scott!

i always assumed the electrical engineer laid out the pcb? i thought they went hand in hand. electrical Engineering and pcb design ...

This is so informative.. Thanks

I want to hear practices experiences from this video. Such a tech base , Engineers have been already known, I thinks so. In particular, In RF PCB design of practice.

Can you suggest a software to me for doing mix signal analysis. I have to design and POE++ device with Power Source side and PD controller side to power up high power LEDs like 70W. Client requires detailed simulation prior to making the hardware. I have seen LTSpice but it doesn't support micro-controllers. Candace tools are super expensive. ...what are my low cost options.

I can't find the articles on the website he talks about in the beginning.

was there like two people in the audience?

great presentation, thanks.

Thanks for the nice presentation.

terrible sound, can't hear you on my laptop speakers hardly

Very informative video, thank you!

Great video! I have 1 question on the slide (at time 31:30) the "thermal pad" for the fet is connected to SW. How do you provide cooling for that fet and keep the SW node small?
