## 2. Design Considerations
### Common Design Pitfalls and Solutions
Pitfall 1: Inadequate Thermal Management
- Problem : Excessive junction temperature leading to thermal shutdown
- Solution : Implement proper heatsinking and ensure adequate airflow
- Implementation : Use thermal vias under the package and copper pour for heat dissipation
Pitfall 2: Input Voltage Transients
- Problem : Voltage spikes exceeding maximum ratings
- Solution : Add input transient voltage suppression
- Implementation : Install TVS diodes and input capacitors close to the device
Pitfall 3: Output Instability
- Problem : Oscillations due to improper compensation
- Solution : Follow manufacturer's compensation guidelines precisely
- Implementation : Use recommended capacitor and resistor values for compensation network
### Compatibility Issues with Other Components
Input Filter Compatibility
- Ensure input capacitors have low ESR (typically <100mΩ)
- Avoid using ceramic capacitors with high voltage coefficient
- Recommended: X7R or X5R ceramics with proper derating
Load Compatibility
- Compatible with digital loads (FPGAs, processors)
- May require additional filtering for sensitive analog circuits
- Not recommended for directly driving inductive loads without protection
Microcontroller Interface
- Power-good output compatible with 3.3V and 5V logic
- Enable pin requires proper sequencing with input voltage
### PCB Layout Recommendations
Power Path Layout
- Keep input capacitors within 5mm of VIN and GND pins
- Use wide traces for high-current paths (minimum 40 mil width for 3A)
- Place output capacitors close to the device with minimal trace length
Thermal Management
- Use 4×4 array of thermal vias under the exposed pad
- Connect thermal pad to large copper pour on PCB
- Consider using thermal interface material for high-power applications
Signal Routing
- Route feedback traces away from switching nodes
- Keep compensation components close to the device
- Use ground plane for noise immunity
General Guidelines
- Minimum clearance: 8 mil for signal, 20 mil for
