## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Decoupling
- Problem : Poor high-frequency performance due to insufficient local energy storage
- Solution : Implement multi-stage decoupling with 100nF ceramic capacitors placed within 5mm of power pins, supplemented by 10μF bulk capacitors
Pitfall 2: Thermal Management Issues
- Problem : Premature thermal shutdown during high-load operation
- Solution : Calculate maximum power dissipation (Pdiss = (Vin - Vout) × Iout) and ensure adequate copper area for heatsinking (minimum 2cm² per watt)
Pitfall 3: Ground Loop Formation
- Problem : Signal integrity degradation from improper grounding
- Solution : Implement star grounding topology with separate analog and digital ground planes connected at a single point
Pitfall 4: Layout-Induced Noise
- Problem : Switching noise coupling into sensitive analog circuits
- Solution : Maintain minimum 3mm clearance between switching nodes and sensitive traces, use guard rings where necessary
### Compatibility Issues with Other Components
