### PCB Layout Recommendations
Power Stage Layout
```
Critical Path: Vin → Input Caps → IC → Output Caps → Vout
```
- Place input capacitors within 5mm of Vin pins
- Use multiple vias for power and ground connections
- Maintain continuous ground plane beneath IC
Thermal Management
- Use 4oz copper for power planes
- Implement thermal relief patterns
- Provide adequate clearance for heatsink mounting
Signal Routing
- Keep feedback traces short and away from switching nodes
- Route compensation components adjacent to IC
- Separate analog and digital ground domains
