RECOM recommends a PCB layout with a large copper area connected to the tab of the R-78B6.5-1.0 to dissipate heat efficiently. A minimum of 1 square inch of copper area is recommended.
To ensure the R-78B6.5-1.0 operates within its SOA, monitor the input voltage, output current, and ambient temperature. Ensure the device is not subjected to excessive voltage, current, or temperature stress.
RECOM recommends using a low-ESR ceramic capacitor with a value of 10uF to 22uF, X5R or X7R dielectric, and a voltage rating of 10V or higher.
While the R-78B6.5-1.0 is a high-quality device, it is not specifically designed for high-reliability or aerospace applications. For such applications, consider using a device with a higher reliability rating, such as a MIL-PRF-38534 or ESCC-certified device.
To troubleshoot issues with the R-78B6.5-1.0, check the input voltage, output voltage, and output current. Verify that the device is properly soldered and that the PCB layout is correct. Consult the datasheet and application notes for guidance.
