A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short and wide traces for the power lines.
Use a thermal pad or a heat sink to dissipate heat, and ensure good airflow around the IC. Also, reduce the ambient temperature and avoid high-power operation for extended periods.
The maximum input voltage is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
Check the input voltage, output load, and PCB layout for any issues. Use an oscilloscope to monitor the output voltage and current. Also, verify that the input and output capacitors are of the correct type and value.
Yes, the RT8079GQW is suitable for high-reliability and automotive applications, but ensure that you follow the recommended operating conditions and PCB layout guidelines. Also, consult with Richtek Technology Corp for any specific requirements or certifications.
