## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Input Capacitor Selection
- Problem : Insufficient input capacitance causing voltage droop during load transients
- Solution : Use low-ESR ceramic capacitors close to VIN and PGND pins
- Implementation : Minimum 2×22μF X5R/X7R ceramic capacitors + 100μF bulk capacitor
Pitfall 2: Poor Thermal Management
- Problem : Excessive junction temperature leading to thermal shutdown
- Solution : Implement proper PCB thermal vias and copper pours
- Implementation : Use 4oz copper, thermal vias to ground plane, consider external heatsink
Pitfall 3: Incorrect Feedback Network Design
- Problem : Output voltage instability or inaccurate regulation
- Solution : Use 1% tolerance resistors in feedback divider network
- Implementation : Place feedback components close to FB pin, avoid noisy areas
Pitfall 4: Inadequate Output Filter Design
- Problem : Excessive output ripple or poor transient response
- Solution : Optimize LC filter values based on load requirements
- Implementation : Calculate inductance using ΔIL = (VIN - VOUT) × D / (fSW
