BU69090NUX-TR Frequently Asked Questions (FAQs)

  • ROHM recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • Follow the recommended operating temperature range (-40°C to 125°C) and ensure proper thermal design, including heat sinking and airflow. Also, consider derating the device's power dissipation according to the temperature derating curve in the datasheet.
  • ROHM recommends a 10uF to 22uF ceramic capacitor (X5R or X7R type) with a voltage rating of 10V or higher, placed as close as possible to the VIN pin.
  • Check the input voltage, output load, and PCB layout for any issues. Ensure the output capacitor is properly sized and placed, and the feedback network is correctly configured. Also, verify that the device is not operating in a region of instability, such as near the minimum or maximum output voltage.
  • The maximum allowed output current is 2A, but it's recommended to derate the current according to the ambient temperature and the device's power dissipation to ensure reliable operation.
