Hi, I can review your completed medical IVD power supply schematic before PCB layout, focusing on reliability, EMI/EMC performance, protection circuits, component values, and IEC 61010 / IEC 61326 compliance readiness. The best solution is to first review the full 12V input path, buck converter, 3.3V LDO, fuse, TVS, reverse polarity protection, CMC, ferrite beads, ESD protection, EMI filters, and analog/digital power distribution. Then I’ll identify design risks, weak protection points, noise concerns, and layout-sensitive areas before you move to PCB design. I’m comfortable with power electronics, DC-DC buck converters, low-noise power design, LDO review, EMI/EMC filtering, ESD/TVS protection, medical/IVD electronics, IEC 61010 awareness, IEC 61326 EMC considerations, CISPR-style concerns, and compliance-oriented schematic review. Deliverables will include: * Reviewed schematic comments * Component/value verification * Buck and LDO review * Protection circuit review * EMI/EMC improvement suggestions * Power integrity concerns * PCB layout recommendations * Reliability improvement notes * Final design review report I’ll focus on finding issues early, improving first-pass compliance chances, and giving practical recommendations before PCB layout starts. Best regards Ankit
