MD-90 Frequently Asked Questions (FAQ)
-
CUI recommends a 4-layer PCB with a solid ground plane and a separate power plane for the DC-DC converter. The input and output capacitors should be placed close to the converter, and the feedback resistors should be placed close to the output voltage sense pins.
-
To ensure reliable start-up, make sure the input voltage is within the specified range, and the input capacitance is sufficient to handle the inrush current. Also, ensure that the output voltage is not pre-biased before the MD-90 is enabled.
-
The maximum allowable output capacitance for the MD-90 is 220uF. Exceeding this value may cause instability or oscillation in the converter.
-
The MD-90 is rated for operation up to 85°C ambient temperature. However, derating may be necessary for high-temperature applications. Consult the datasheet for derating curves and thermal management guidelines.
-
To troubleshoot issues with the MD-90, check the input voltage, output voltage, and output current. Verify that the input and output capacitors are within the recommended values, and that the PCB layout is correct. Consult the datasheet and application notes for troubleshooting guidelines.
