Murata recommends a PCB layout with a solid ground plane and a minimum of 2 oz copper thickness to ensure optimal thermal performance. Additionally, keeping the component away from heat sources and using thermal vias can help to reduce thermal resistance.
To ensure reliable start-up, it is recommended to follow the recommended input voltage ramp-up time and to ensure that the input voltage is within the specified range. Additionally, using a soft-start circuit or a voltage supervisor can help to prevent start-up issues.
The maximum allowable capacitance for the output filter capacitor is not explicitly stated in the datasheet, but as a general rule, it is recommended to keep the output capacitance below 10uF to prevent stability issues. However, it is recommended to consult with Murata's application engineers for specific guidance on output filter design.
While the 77203HVC is a high-quality component, it is not specifically designed for high-reliability or aerospace applications. For such applications, it is recommended to consult with Murata's application engineers to determine the suitability of the component and to discuss any necessary screening or testing requirements.
To troubleshoot issues with the converter's output voltage regulation, it is recommended to check the input voltage, output load, and output voltage feedback loop. Ensure that the output voltage sense lines are properly connected and that the feedback resistors are correctly selected. Additionally, checking the converter's output voltage ripple and noise can help to identify any issues with the output filter design.
