78602/4C Frequently Asked Questions (FAQs)

Murata recommends a symmetrical PCB layout with a solid ground plane, and keeping the input and output traces as short as possible. A 4-layer PCB with a dedicated power plane and a solid ground plane is also recommended.
To ensure reliability, Murata recommends following the derating guidelines for temperature and output current, and using a heat sink or thermal interface material to reduce the junction temperature. Additionally, ensure good airflow and avoid thermal hotspots.
The maximum allowable capacitance for the output filter capacitor is 10uF. Exceeding this value may cause instability or oscillation in the converter.
While it's possible to use a different inductor value or type, it's not recommended as it may affect the converter's performance, efficiency, and stability. Murata recommends using the specified inductor value and type to ensure optimal performance.
To troubleshoot issues, start by checking the input voltage, output voltage, and output current. Verify that the input and output capacitors are properly connected and meet the recommended specifications. Check for any signs of overheating, and ensure that the converter is properly soldered and mounted.
