In this video I'm examining and repairing my faulty USB phone charger (5V 1A switching power supply). It failed after 2 years of seldom use. I've drawn a partial schematic in the video. Full reverse engineered schematic of this charger is here:

Dude, I'm a technician and this is about the only size circuit I would attempt to troubleshoot. Trying to troubleshoot more advanced circuit systems like phased array radar systems and circuitry with analog and digital circuitry on the same board can be stressful and frustrating. This is a great starter circuit to learn how to troubleshoot. BTW, the guy doing this video would make a great electronics teacher.

Ahhh... those broken radar things that must be fun, lol here he didn't troubleshoot much,just replaced parts until he got it; did not even look at the board to see if there was any obvious contamination; it is all another utube trick to get views, because he had smelled the leaked electrolite, he **knew** it might need moping up;

Yeah the guy has an accent, but I bet 90% of those people making fun of him does not speak a foreign language, not even has the knowledge he does. So lets stop making fun and start learning ;) The content is VERY GOOD and he is speaking a very understandable english, I am not a native english speaker and I understand everything, in the end of the day that is what really matters. Come on, he could easily speak his native language and we would never understand it. Thanks for the good informative video.

Before scrolling down to the comments, I also guessed lots of commenters would have fun with the voice. Its funny, but easy to hear anyway, because of good audio quality. But more important - this man is a electonics professional. He obvious knows alle the individual details and functions/principals of the switch-mode power supply circuits, so listen and learn... Pay special attention to the evaluation of the isolation band between the high voltage and low voltage section. Important safety.... Thanks to this DiodeGoneWild for using so much time on an $5 unit. You know your knowlegde.

That makes you racist. Against white people. So you've proven yourself wrong. Racism doesn't spare white people either. I do agree that racism is stupid, though. You demonstrate that quite well. But the more people continue to talk about it, the longer they keep it alive. If everyone could forget about it & simply hold individuals accountable for their own actions, then racism would be a thing of the past. As Gandhi said, "Be the change you wish to see in the world."

I think the 6Z2 chip is actually a dual common anode zener diode. As for the emitter of the switching transistor - it probably connects to the chip because the chip has an internal current sensing resistor or something like that, for overcurrent/overpower protection.

The control IC is definitely made by Diodes but the mark doesn't match any known device so it's either a custom chip for this supply or it's mismarked. That is fairly standard topology to have the sense resistor going into the controller and the transistor collector on another pin. The device on the output is definitely a minimum load to prevent the output from exceeding 5V.

5:35 The extra resistor to the negative rail means that it will be a voltage divider, it will give a fixed voltage to the "chip" if this is resistor was not there, it would mean it is only the current to the chip would be reduced, NOT the voltage (although, in practice, the voltage would probably be reduced a lot). This is the difference between a Rheostat, which has 2 connections and controls current and a Potentiometer which has 3 connections and controls voltage. Hope this helps mate :-)

It seems that only 10% of the subs really watch the videos. Maybe they have subbed to too many channels because the youtubers are desperately begging for subs those days :D. 1/3 of the voltage would be 110Vdc. The chip has to clamp it down to a much lower voltage anyway, so the 22M resistor at the bottom has no use. Maybe they had a big stock of 22M resistors with no use...

hi guys i have a problem: the input of the same USB charger as you is in my country 230V, but can i also put there an Input, negative and positiv cable of a 12V Batterie, on it? or doesn't it work bc of a diode?

Have a slightly different Samsung adaptive fast charge model for the 120V 60Hz market, quit on me after two years. Turned out it was a manufacturing defect, the PCB slides into two connectors to hook it up to mains power and one had failed by inadequate contact. Bent the connector so it grips more tightly and replaced the solder on the PCB connecting pad. Works now, got lucky with a super simple problem.

His way of speaking sounds like a song! Nice job by the way :) The 22+22 MegaOhms and the 22MegaOhms seems to be a voltage divider for providing the bias voltage to the base of the transistor. Probably the switching of the transistor is done by the pin from "Mysterious Circuitry 8-pin chip". This chip must have some internal switch to connect and disconnect the transistor's emitter to ground (could be used for over-current/over-voltage cut-off or something).

The input capacitors are made by CapXon. A capacitor company that makes their capacitors in china. CapXon is also notorious for their capacitors failing prematurely. Especially around the early 2000's, Capxon's newer capacitors are not that much better. They should have gone with a better brand for the input capacitors, Some really good brand they could have gone with are nippon chemi-con, nichicon, rubycon, panasonic and suncon. (most of these brands make there capacitors in japan.) REPLY

I was thinking to myself when editing this comment today 'Should i remove the part about the Chinese capacitors being "decent" ' I guess i should now because now I've seen more of them fail since i made that comment.

Ben Chavez - when you were editing, you should have fixed the repeated errors in the use of there, their and they're. There was a dead capacitor in this charger. They're all cheap Chinese capacitors inside there, and the brands are notorious for their low quality.

I find myself randomly talking to myself out loud or in my head using your accent even when I’m in public. It’s not that I’m making fun of you per se… it’s just fun to talk like that and yes it is kind of comical so I guess I’m kind of poking fun. But I don’t mean to offend you, becauseI find your accent very endearing and calming to listen to. Especially when trying to sleep after a long day in the lab and my mind is racing with projects and business ideas. But it’s pretty hilarious when I catch folks looking at me strangely when talking to myself out loud and over exaggerating your wild accent out in public and not realizing it. 😂
