Murata recommends a 2-layer PCB with a solid ground plane on the bottom layer and a thermal relief pattern on the top layer to ensure optimal thermal performance.
To ensure reliable start-up, ensure that the input voltage is within the specified range, and the output capacitor is properly sized to handle the inrush current. Also, ensure that the input voltage rise time is slower than 10ms to prevent false triggering of the UVLO.
The maximum allowed capacitance for the output filter capacitor is 220uF. Exceeding this value may cause instability or oscillation in the converter.
While it's possible to use a different inductor value, it's not recommended as it may affect the converter's performance, efficiency, and stability. The recommended inductor value is carefully selected to ensure optimal performance.
To troubleshoot issues with the output voltage regulation, check the input voltage, output load, and feedback resistors. Ensure that the feedback resistors are properly selected and the output voltage sense lines are properly connected.
