With over 8 years of experience in electrical engineering and a specialization in PCB design, I'm confident I can deliver exactly what you are looking for on this Qi smartphone charger schematic project. Firstly, as a preferred freelancer, I have had the privilege of working with various CAD formats including Altium, KiCAD, and Eagle - ensuring that I can provide a schematic layout that fits seamlessly with your existing CAD tools. My ability to work with EasyEDA is an added bonus as I hold a professional certificate in this field. Secondly, my proficiency extends beyond simply designing a schematic. What you need is more than just the design - you need a bill of materials analysis and design notes among other things to ensure smooth sailing when it comes to production and testing. My skill set includes these vital aspects to make sure your device meets all necessary thermal and safety standards. Lastly, my familiarity with major computing firms like TI, NXP, ST as well as the Chinese Qi reference chipsets can indeed help expedite your certification process as it allows me to pull from vast knowledge acquired while using these proven ICs. I'm here to transform your ideas into successful products; I'm ready to go the extra mile if needed

I came across your project for the smartphone charger schematic design and I have to say, it sounds like a really interesting challenge. I've been working on power electronics and embedded systems for about six years now, and I genuinely enjoy projects that require careful attention to safety and efficiency. I can handle the full schematic capture and component selection to make sure everything from the input protection to the output regulation is solid. I also have experience with PCB layout and prototyping, so I can take this beyond just a schematic if needed. I'd love to hear more about your specific requirements and timeline.

Hi, I’ve worked on similar wireless charging and high frequency power electronics projects, including Qi transmitter designs using TI, NXP, and Chinese reference chipsets. I’m familiar with the complete design flow from the AC/DC front end to the resonant transmitter stage, including FOD protection, thermal management, tuning networks, and Qi power negotiation. I can provide complete schematic designs for 15W, 18W, 22.5W, 30W, and 40W wireless chargers using proven Qi transmitter architectures suitable for PCB prototyping and certification preparation. The deliverables will include: • Production ready schematic files in Altium or KiCad • BOM with widely available components from major distributors • Coil and resonance tuning recommendations • Thermal and safety implementation notes • FOD, over current, and over temperature protection design • Suggested test points for resonance and power verification • Notes for PCB layout, EMI handling, and thermal dissipation I’ve previously worked with programmable Qi controllers where firmware configuration, power negotiation, and protection calibration were required, so I can also provide guidance for firmware hooks if the selected chipset requires configuration. I understand the higher power variants require careful handling of thermal performance, coil selection, and stable communication with Qi compatible smartphones, especially above standard EPP power levels. Best regards, Ihor

I will deliver a production-ready, highly optimized schematic for your multi-tier (15W to 40W) wireless charging project using proven, certifiable chipsets (ST, NXP, or optimized Chinese reference designs). My design will cover the full signal path—from the front-end protection circuits to the resonant coil driver. I will implement hardware-level Foreign Object Detection (FOD), precise tuning networks for standard Qi coils, and robust thermal protection. You will receive clean, hierarchical CAD schematics (Altium/KiCad), an active MPN-backed BOM ready for major distributors, and comprehensive design notes with designated bring-up test points. Ready to start immediately.
