Quasi-resonant SMPS with ICE5QR0680AZ
Details about the project are on my blog where I also have details about calculations, calculations that are made with Gemini AI and later verified based on theory: https://vlad-gheorghe.blogspot.com/2026/05/smps-cu-ice5qr0680az.html
The PCBs are unexpectedly well made, super high quality, and the additional pads made by PCBWAY resulted in decent cooling for the IC compared to the test version made on one side.
