## 2. Design Considerations
### Common Design Pitfalls and Solutions
Gate Drive Issues
- Pitfall : Insufficient gate drive current causing slow switching and increased losses
- Solution : Implement dedicated gate driver IC with peak current capability >2A
- Pitfall : Excessive gate resistor values leading to switching speed reduction
- Solution : Optimize gate resistor values (typically 2.2-10Ω) based on switching frequency
Thermal Management Problems
- Pitfall : Inadequate heatsinking causing thermal runaway
- Solution : Use thermal vias and proper copper area (minimum 2cm² per device)
- Pitfall : Poor thermal interface material application
- Solution : Apply appropriate thermal compound with controlled thickness
Layout-Related Issues
- Pitfall : Long gate trace lengths causing ringing and oscillations
- Solution : Keep gate drive loops compact (<10mm trace length)
- Pitfall : Insufficient decoupling near power pins
- Solution : Place 100nF ceramic capacitors within 5mm of device pins
### Compatibility Issues with Other Components
