Excellent Video! The bit about how the PWM control works with the error amplifier and PWM ramp was actually very opening. That part of buck regulator topology was always a bit hand-wavy to me until now. Thanks!
Hello Paul - sorry this is such a late reply. The simplest way to check a switching regulator is to connect and apply the proper input voltage, enable the regulator, and then check the output with a multimeter, to verify if it is regulating at the expected voltage. If you need more in-depth debugging, I would say the next step is to probe the "switch node" (e.g., the input side of the inductor, in a buck regulator) and look for appropriate switching waveforms - typically, square pulses of more or less constant width and more or less constant periodicity. Beyond that - you really have to know a bit about the topology and control method of the regulator.

Sir, this is the best explanation ive ever heard. Thanks!
Comprehensive course with a smooth delivery : grey haired analog wizards ftw ;-) thanks for publishing this series.

Very good video on the basics of switching regulators. Thank you !
oh, that's beyond my knowledge right now, I hope I'll be able to comprehend that later, very impressive
Excellent lecture
Great explanation
Best seen so far!
Glad you liked it!
15:24 the narrative deviates significantly from the slide content, so we never really get an explanation of how the buck regulator works.
Is it possible to get the slide?
14:48 It is not a Flyback topology, it's a Buck-Boost inverting topology!
How do I check a switching regulator if its working properly or if its "dead" ?

Excellent video, pouvez-vous traduire en french et si possible cours en pdf; merci .
Hello Maxim marketing - this is a great video, but I wish the presenter had introduced himself at the beginning.
