6. Revision-Specific Notes (Rev 10)

• Expect minor footprint adjustments, repositioned components for manufacturability, added test points, or corrected silkscreen labels.
• Look for revision callouts near the board title block (e.g., “Rev 10”) and change-history notes that indicate relocated nets or replaced parts.
• If available, consult the revision changelog or BOM to map schematic differences (e.g., resistor value changes, alternative footprints).

3. Signal & Power Flow (Top to Bottom)

1. Mains AC → Fuse & MOV → EMI filter.
2. Rectified DC → Bulk capacitor → Transformer primary & MOSFET drain.
3. Controller IC generates gate pulses → MOSFET switching → energy stored in transformer.
4. Auxiliary winding → rectified/diode → feeds VCC pin of IC1.
