## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Insufficient Input Capacitance
- Problem : Input voltage ringing during load transients
- Solution : Use low-ESR ceramic capacitors (X7R/X5R) close to VIN and GND pins
- Recommendation : Minimum 22µF bulk capacitance plus 100nF decoupling
Pitfall 2: Improper Inductor Selection
- Problem : Excessive ripple current or instability
- Solution : Select inductor based on maximum ripple current (30-40% of IOUT)
- Calculation : L = (VIN - VOUT) × VOUT / (VIN × fSW × ΔIL)
Pitfall 3: Thermal Management Issues
- Problem : Premature thermal shutdown
- Solution : Implement proper PCB copper area and thermal vias
- Guideline : Minimum 1.5cm² copper area per amp of output current
### Compatibility Issues with Other Components
Digital Control Interfaces
- Compatible with 3.3V and 5V logic levels
- May require level shifting when interfacing with 1.8V microcontrollers
- Enable pin has 1.2V typical threshold voltage
Analog Sensing Circuits
- FB pin impedance: 1MΩ typical
- Compatible with external precision resistors (0.1% tolerance recommended)
- Avoid routing sensitive analog traces near switching nodes
