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
15:24 the narrative deviates significantly from the slide content, so we never really get an explanation of how the buck regulator works.
Best seen so far!
Glad you liked it!
Great explanation
Excellent lecture
Is it possible to get the slide?
How do I check a switching regulator if its working properly or if its "dead" ?

14:48 It is not a Flyback topology, it's a Buck-Boost inverting topology!
Hello Maxim marketing - this is a great video, but I wish the presenter had introduced himself at the beginning.
