## 2. Design Considerations
### Common Design Pitfalls and Solutions
Thermal Management Issues:
- Pitfall : Inadequate heat sinking leading to premature thermal shutdown
- Solution : Implement proper thermal vias and copper pours; use thermal simulation tools during design phase
Stability Problems:
- Pitfall : Output oscillation due to improper compensation network
- Solution : Follow manufacturer's recommended compensation component values; verify stability with load transient testing
EMI Compliance Challenges:
- Pitfall : Failing radiated emissions tests
- Solution : Use recommended input filter topology; maintain proper grounding scheme
### Compatibility Issues with Other Components
Input/Output Capacitors:
- Requires low-ESR ceramic capacitors (X7R or better)
- Incompatible with high-ESR aluminum electrolytic capacitors
- Minimum 22µF bulk capacitance required on input side
Inductor Selection:
- Must use shielded power inductors with saturation current rating ≥ 150% of maximum load current
- Avoid unshielded inductors to prevent EMI issues
Microcontroller Interfaces:
- Compatible with 3.3V and 5V logic levels
- Requires pull-up resistors for enable/power-good signals
- May need level shifters when interfacing with 1.8V systems
### PCB Layout Recommendations
Power Stage Layout:
- Keep input capacitors (CIN) within 5mm of VIN and GND pins
- Place inductor (L1) close to SW pin with minimal trace length
- Output capacitors (COUT) should be positioned adjacent to inductor
Thermal Management:
- Use 4×4 array of thermal vias (8-12 mil diameter) under thermal pad
- Connect thermal pad to large ground plane on inner
