SDR-70 Frequently Asked Questions (FAQs)
-
CUI Devices 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 as close as possible to the device, and the feedback resistors should be placed close to the output capacitors.
-
The SDR-70 has a thermal pad on the bottom of the package that should be connected to a thermal plane on the PCB. A thermal interface material (TIM) can be used to improve heat transfer between the device and the PCB. Additionally, the PCB should be designed to allow for good airflow around the device.
-
While the datasheet specifies a maximum input voltage of 36V, it's recommended to derate the input voltage to 32V to ensure reliable operation and to prevent damage to the device.
-
The SDR-70 is rated for operation up to 85°C, but it can be used in higher temperature environments with some derating. However, the device's reliability and lifespan may be affected. It's recommended to consult with CUI Devices' application engineers for specific guidance on high-temperature operation.
-
CUI Devices recommends following a systematic troubleshooting approach, starting with checking the input voltage, output voltage, and current. The device's enable pin should also be checked to ensure it's properly biased. If issues persist, it's recommended to consult the datasheet and application notes, or contact CUI Devices' technical support team.
