Fake Samsung charger with interesting circuitry

Ғылым және технология

I had another go at getting this thing to communicate with various devices and step the voltage up for higher power delivery, but drew a blank. It just didn't happen.
It would have been handy to have a USB-C breakout PCB to check voltages, since the middle output didn't seem to activate at all, even for 5V.
This is one of many clone power supplies being sold on eBay at a higher price than a safe and compliant charger from somewhere like IKEA. There's absolutely no guarantee of safety with the grey import units. A good USB charger is an essential part of modern digital life, so it pays to get a good one and also a decent cable for your higher power items. These units from unaccountable sellers often pose a high shock and equipment damage risk through cost cutting and bad design.
The circuitry is quite intriguing because of the way they have implemented the ability to initially have a standard 5V supply, but then allow two different ICs to negotiate a higher voltage with the connected equipment and then override the preset 5V reference to raise it to the desired level.
The two power supply modules are quite unusual for having separate rectifiers and smoothing capacitors on the primary side. They could have used a single rectifier and smoothing capacitor. I wonder if it's to avoid interaction, or just based on a duplicated single power supply design.
The use of a TL431 shunt regulator with a near-50/50 divider to hit its threshold of 2.5V with a supply rail of 5V is quite neat.
The primary side control chips are almost certainly a clone of another prominent IC like a Viper 22A

This also keeps the channel independent of KZread's algorithm quirks, allowing it to be a bit more dangerous and naughty.

    I've designed this type of circuit for work. The SDC5091 is a saturation flyback driver IC. It has a depletion mode FET that ties the 2.2uF cap as a bootstrap supply. The IC also has a power MOSFET on pins 5-8. These normally have pin 1 and the bottom as ground. The IC turns on the MOSFET, charging the primary side of the flyback transformer. The opto-isolator triggers the IC to turn off the MOSFET when the core of the flyback reaches saturation. As the magnetic field collapses, it is forced into the secondary side, providing power to the output. When the core is no longer saturated and the output starts to dip, the opto-isolator turns off, triggering the IC to turn on the MOSFET again. The odd configuration of the freewheel/snubber circuit is because you want the primary side to be able to reach a highish voltage while the field collapses into the secondary, but not too high that it damages the MOSFET, or puts the body diode of the FET or MOSFET into conduction. This circuit could just be the resistor and capacitor, but there is a high likely hood of unwanted oscillations. So, the diode is added to eliminate any oscillation. It is common for this diode to be a power zener, or a TVS depending on input supply and flyback specs.

    The simple 1 USB port fake black Samsung chargers can be identified by the part number printed on the outside. That part number on the fake one is ETA-U90EWE, which is actually the part number on the white original Samsung charger. The genuine black Samsung charger uses ETA-U90EBE as part no. So I bet this "mistake" in part no can also be the case with other fake Samsung charger types. I used some of those fake Samsung type 1 single USB port chargers for a while, until one night in 2018 when I was still awake and charging my smartphone in the other room when suddenly heard circuit breakers tripping and all the power in the house when off. I found my way to the fuse panel and found out that the fuse on the wall outlets and main switch had blown. So I pushed them both back on, and they stayed on, but suddenly I smell something burning. I took a tour of the house and when I got to the room where my smartphone was charging I found the culprit. That fake Samsung charger was burning with an eight inch flame around it, I ripped the charger from the power strip by pulling the USB cable, and threw it into the sink where I was able to extinguish it with water. Fortunately, the smartphone was not damaged, and i was still awake when this occured and could take action. I have smoke detectors in almost every room,and also in the room where this occured, but the fire started on the otherside of the room then where the smoke detector is installed. Never used a fake charger for a smartphone again since that day.

    Hey Clive. rather than worrying about "plugging expensive devices" into "questionable" PD chargers, you might consider getting some cheap Power Delivery "decoy" boards. These things cost from a couple bucks each up to about fifteen for a fully programmable unit. The most basic ones spoof the PD charger for a single voltage and provide + & - measurement / connection points, slightly more advanced models have short-able pads to select the PD output voltage, and the most advanced modes cost around 15 bucks and use a push-button and colored LED system to program the output. So instead of risking any PD equipment, you can just decoy the different voltages, measure them with a meter & apply a load if you so desire.

I think there's also some PD trigger stuff in the my drawer too, but I can't remember now. Aliexpress has plenty of choices, which makes me think eBay will too.

    You can bet USB PD "trigger" boards that go inline with the dummy load. I have some adjustable ones that let me request a voltage.

It can check the charger and cable for every fast charge ability, and also it can force quick charge voltages for any voltage you want then you can test the amp load on the usb c or a output. It also shows voltage ripple graph/oscilloscope down to 3.1 uS and 1mV Can estimate calculate charged current to a 3.6v lipo battery, and is actually within 5% from factory (can adjust conversion efficiency on it for the calculation) I love it and it have revealed one super fake charger

    Clive, coming back to this video now that I know a bit more about things... The reason the feedback circuit doesn't just flip in different resistances is so the supply can vary the output voltage as the device requests, via the Programmable Power Supply (PPS) feature added in the USB PD 3.0 spec. The idea is optimizing the input voltage to best charge the battery. As for the two independent supplies, this makes sure one of the outputs can supply max wattage, while the other two are splitting up the wattage capability of the other supply. The other two ports have to be at the same voltage, and if you connect something, the other port will temporarily shut off while it re-negotiates. There's definitely some excess duplication, though, and no way can this do 65W. As for not wanting to plug expensive devices in, there are newer USB testers that can query and negotiate with PD and QC2.0/3.0 supplies. It's great for seeing what they support, and triggering the higher voltages to feed into a load tester. I personally like my FNB58, but there are other options on the market.

    I used to have a handheld game player ( PSP!/MP5! 10,000 games! ) that was basically a Nintendo-onna-chip with a few support ICs to give FM radio, MP3 playback and ( limited ) video playback. It was surprisingly good for NES/SNES/GB/GBC/GBA emulation. The radio worked, with headphones, and MP3 playback was acceptable. Good battery life too. The screen was clear and bright. One day though, it failed to charge. 'Spicy pillow' was my first thought. Sure enough, the battery needed either Benadryl or Viking funeral. It got the latter. Nestled between the battery and back panel was a strip of heft adding steel. It didn't need it. It was a good product at a keen price. I mackled a BL-5C clone battery in and got another years use from it before mislaying it somewhere. That strip of steel made me chuckle at the time. That it's still being done a decade or so later?, not quite so funny.

    The chip marked 6606ACA is a Fitipower FP6606AC, which is a dual USB-C PD/QC and USB-A QC charger controller. The last letter denotes what list of USB PD voltage/currents will be presented to a PD-capable device; the A suffix means the USB PD protocol will present 5V/3A, 9V/2A, and 12V/1.5A. The chip marked N603 I couldn't find information for, and searching for an FP6603 didn't turn up any useful data (but there is a datasheet for an FP6601 and it seems similar enough in pinout). From what I can tell it is just a QC controller that looks at the D+/D- lines, but I can't quite make out what is going on with the CC identification lines on that board since it's not a simple 56k pullup resistor to indicate a USB-C power source.
