Pitfall 2: Poor Thermal Management
- Problem : Overheating due to insufficient heat sinking
- Solution : Implement thermal vias, adequate copper area, and proper heat sink selection
- Implementation : Calculate thermal resistance and ensure TJ remains below 150°C
Pitfall 3: Layout-Induced Oscillations
- Problem : Parasitic inductance causing ringing and EMI issues
- Solution : Minimize loop areas and use proper decoupling capacitor placement
- Implementation : Place decoupling capacitors close to drain and source pins
### Compatibility Issues with Other Components
