## 2. Design Considerations
### Common Design Pitfalls and Solutions
Input Capacitor Selection
*Pitfall:* Insufficient input capacitance causing voltage spikes and instability
*Solution:* Use low-ESR ceramic capacitors (X5R/X7R) close to VIN pin
- Minimum 10μF bulk capacitance recommended
- Parallel combination of 1μF and 10μF for optimal performance
Output Filter Design
*Pitfall:* Improper LC filter values leading to output ripple and instability
*Solution:* Follow manufacturer's inductance and capacitance guidelines
- Inductor saturation current should exceed 1.5× maximum load current
- Output capacitor ESR critical for stability - use recommended values
Thermal Management
*Pitfall:* Inadequate heat dissipation causing thermal shutdown
*Solution:* Implement proper PCB copper pours and thermal vias
- Minimum 2 oz copper weight recommended for power traces
- Use thermal relief patterns for improved heat transfer
