7. Efficiency and Thermal Considerations

• Efficiency depends on VIN, VOUT, load, MOSFET Rds(on), switching losses, and inductor losses. Expect highest efficiency at mid-load region (0.5–2 A).
• Thermal design: calculate power loss = VIN × IIN − VOUT × IOUT. Use measured efficiency to approximate dissipation. Ensure PCB copper and thermal vias under exposed pad to spread heat. For continuous 3 A at large VIN–VOUT drop, evaluate the case temperature and derate accordingly.
