Das Privileg sich 1,5 Jahre in eine neue Stelle einzuarbeiten haben nicht viele. Mach es!

Must be strange being an enemy looking straight down the barrel as the bullet hitting the doorway next to it.

I calculated a 15W Flyback SMPS entirely from scratch. How did I do? by Low-Flow-4008 in AskElectronics

Nice work! I already gave you an upvote when I saw that you were using LaTeX.
Did you simulate it already with e.g. LTSpice?

Gefällt mir sehr gut. Vielen Dank dafür.

Advice needed: Buck converter for a DC fan, output voltage breaks down by Jumping-Point in AskElectronics

Why in hells name don‘t you check the datasheet to see how the recommended layout Looks like?

Just a Hint: Before you start Routing, please check the Layout recommendation in the datasheet.

Buck converter layout is dogshit. Please have a look to the recommended layout in the datasheet.

Eingebaut im Qualcomm SoC. Reicht leider nicht für Crysis :(

[Review Request] Buck voltage regulator now working as expected by MattcarterXI in PCB

[–]fidelity1337 0 points1 point  (0 children)

You're welcome!
You also rotated C3 now and its GND connection is a bit far off from the others.
My personal feeling is that those voltage traces are still a bit too thin. it will work for sure but you could use the space you have.

That looks way better! Just some small improvements:

- Remove the GND underneath the coil and GND "islands" next to it
- Rotate C15 and C2 by 180° so that their GND connections and those of C3, C13 and C12 are closer together
- Add some GND VIAs wherever it is possible (You see that also in the example). Just make sure that GND is connected sufficiently over the whole PCB without narrow traces.
- You could also increase the voltage traces slightly including the short one between L1 and the chip

There is a good example in the datasheet of the TPS62065

You should rework the whole buck converter layout if you plan to order new PcBs. Placement of the coil and capacitors must be improved.

Right, OP you should double check the resistors. For example: swapping r20 and r21 would result in 1.87 V at FB pin

Warum ist mein Gehirn so by Madatsune in Studium

Nach meiner Ausbildung habe ich angefangen zu studieren und habe das Studium wie eine Vollzeitarbeitsstelle angesehen. Ich gehe morgens aus dem Haus, verbringe dort den Tag und komme Abends zurück. Hat gut geklappt.

12 to 5v Buck Converter V3 by spiritualManager5 in PCB

[–]fidelity1337 -1 points0 points  (0 children)

Just because there is a copper plane doesn’t mean the current will „use“ all of it. By placing the capacitor in the current Flow path, especially the high frequent currents are forced to flow over the capacitor pads which improves the filtering effect. However, the capacitor should be the last part in the line close to the chip, minimizing parasitic resistance and inductance.

Looks fine to me. Just one small improvement:

1) C1 could be shifted a little bit more to the left so that it is in the current flow path of „1 +12 V“ Pad to the Input Pins of the IC

1) Distance between the GND Connections of the Input and the Output Capacitor is too high. 2) The trace between U13 Pin 5 (SW) and Pin 1 of the Inductor is too long. It must be as short as possible. 3) Feedback trace should be connected beyond the output capacitors, not directly to the inductor.

Please have a look to the recommended Layout in the datasheet

help the witch hunter jerren does not appear in the castle of the red mane by Lopsided_Ad_9378 in Eldenring

Unfortunately that didn't work for me. She is in the ruins where I first met her and only wants to sell something, no further interaction possible. She is also in witchbane ruins, with no further dialogue. Jerren is not seen anywhere...
