Good prep for understanding everything about buck converters

[@RGBEngineering]

thank you :)

[@user-se2pb5yx5p]

i'm glad i watched this. super helpful in understand the circuit.

[@RGBEngineering]

Glad it was helpful!

[@xuio_]

great video! touching on your eureka moments really helped me!

[@RGBEngineering]

I'm so glad!

What switches the mosfet on and off?

[@RGBEngineering]

Great question, that would be the regulator IC. There will be a video all about those soon!

[@3bmon3em]

wow that was really amazing. I hope you stick to the series you start not like other youtubers. that would be really helpful. definitely subbed

[@RGBEngineering]

I already have several videos scheduled for release, so my plan is do definitely stick to the series :)

[@okfuz]

The changes in current can be approximately linear, right? I think an LRC circuit will always produce a logarithmic current curve, it would be more pronounced if for example the duty cycle switching freq. was too slow.

[@RGBEngineering]

Yes, it is okay to linearly approximate the changes in current.

[@user-vi6vc7cm1w]

I guess you missed the logic, when mosfet switches off, inertia current in inductor changes its direction and voltage spike happens which evens out by capacitor.

That was meaningless word salad. How about you comment on something you actually know about!
