- Keep compensation components close to the IC
- Use ground planes for noise immunity
Thermal Management
- Implement thermal vias under the package
- Provide adequate copper area for heat dissipation
- Consider thermal relief patterns for manufacturing
EMI Reduction
- Place decoupling capacitors as close as possible to pins
- Use ground shields for sensitive analog sections
- Maintain proper clearance between high-speed switching nodes and sensitive analog circuits
