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

Thank you for this. I also picked up your article from your website, which shows many of the pictures in your presentation. The first part of the video is just background information on switching supplies, so if one is already familiar with the topic, they may wish to skip ahead to the practical advice starting at about time 18:30.

Really good speaker and an informative video. I'd love to have a beer with this dude and discuss Electronic Design, seems like her really knows his stuff..

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

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

Excellent, thank you! Layout examples were particularly helpful 👍

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

Great presentation and explanation from a PCB Designer prospective.

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

Very informative video, thank you!

Thanks for the nice presentation.

Fantastic presentation! Thanks

Lots of helpful info. Thanks

great presentation, thanks.

This is so informative.. Thanks

wow, excellent talk

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

Good video, thanks.

Thank you!

Great lecture

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?

was there like two people in the audience?

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.

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

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?

Where are the white papers?

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

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

Here from Phil’s lab

does anyone have the ppt?

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.

PCB switching power supplies

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.

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

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.

hes kinda hot

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.
