Design 150W Isolated SMPS (12V 10A + 5V + 3.3V) with PCB & Gerber I need a professional electrical engineer to design a compact, isolated SMPS power supply for a commercial product. ## Requirements: ### Input: * 90–265V AC * PCB-mounted IEC C6 (laptop-type input) ### Outputs: * 12V @ 10A (main rail) * 5V @ 5A * 3.3V @ 3A ### Topology: * Preferred: Flyback (or suggest better if needed for reliability) * Isolation required (safety critical) ### PCB Constraints: * Size: Approx. 35–45 mm width × 120–150 mm length * Compact design for slim enclosure * SMD preferred ### Features: * EMI filter (MOV, NTC, CM choke) * Full protections: OVP, OCP, SCP * Low ripple and stable output * Proper thermal design ### Deliverables: * Complete schematic (annotated) * Transformer design (with winding details) * PCB layout (EasyEDA preferred) * Gerber files (manufacturing ready) * BOM with part numbers * Test points and debugging guide ### Additional Requirements: * Should be suitable for 3-year warranty commercial product * Must follow proper isolation and safety standards Bonus (optional but preferred): * Experience with SMPS >100W * EMI/thermal optimization experience * Prior similar project samples Goal: This will be used in a commercial embedded system, so reliability and manufacturability are very important. Please include your approach and similar past work in your proposal.

Hi, This is a serious power design requirement and I’m glad you’re emphasizing reliability, isolation, and manufacturability, because at 150W, design decisions really matter. I have hands-on experience designing isolated SMPS systems (100W+), including transformer design, EMI compliance, and thermal optimization for compact enclosures.

Hello, your requirement is well-defined and I can help design a reliable 150W isolated SMPS optimized for safety, efficiency, and manufacturability within a compact footprint. I would also like to note that at 150W output, a single flyback may become thermally and efficiency limited; I can evaluate and propose either an optimized high-power flyback or a more robust forward / quasi-resonant topology if needed for long-term reliability. Deliverables: Complete schematic (fully annotated) Transformer design with winding specifications EMI & protection stage (MOV, NTC, CM choke, OVP/OCP/SCP) Compact PCB layout (EasyEDA) Manufacturing-ready Gerber files BOM with exact part numbers Test points + bring-up/debug guide Experience: SMPS / DC-DC converter design PCB design for compact embedded power systems Isolation, EMI reduction, and thermal optimization Embedded hardware integration for commercial systems I focus on practical, buildable designs that pass real-world testing, not just simulation-level concepts. Looking forward to working on this.
