DIY Universal AC-DC Flyback Power Supply (SMPS) Circuit | 12V 3A (36W) | Low Noise & EMI Design ====================================== Altium Designer + Altium-365 (Free): https://www.altium.com/yt/MyVanitar ====================================== Article: ====================================== Schematic/PCB/Gerber/Code: https://365.altium.com/files/87CACF0D... ====================================== Other Videos: http://bit.ly/2N9OlPa ====================================== @AtiumOfficial #altiumstories In this video, I showcase my universal input (85V-260V AC) to 12V-3A DC Flyback power supply, delivering 36W of stable output power. The design uses the OB2273 PWM controller running at 65kHz switching frequency, optimized for efficiency and reliability. I used a 650V Mosfet to drive the transformer. 🔧 Key Features: ✅ Universal AC Input (85V-260V) – Works worldwide! ✅ 12V @ 3A Output (36W) – Perfect for LED drivers, small appliances, and DIY projects. ✅ Low Noise & EMI Design – Careful PCB layout techniques to minimize interference. ✅ Optimized for Conducted Emission Compliance – Follows best practices for cleaner power delivery. ✅ 65kHz Switching Frequency – Balances efficiency and component stress. 📌 Why Watch This Video?
