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 input capacitor is properly sized to handle the inrush current. Also, ensure that the output capacitor is properly sized to handle the output voltage ripple.
The maximum allowable capacitance for the output capacitor is 220uF. Exceeding this value may cause instability or oscillation in the converter.
While the datasheet recommends a specific input capacitor type and value, you can use a different type or value as long as it meets the specified ripple current and voltage ratings. However, this may affect the converter's performance and reliability.
To troubleshoot issues with the output voltage, check the input voltage, output load, and output capacitor values. Also, ensure that the converter is properly soldered and that there are no signs of physical damage or overheating.
