RPI-1035 - ROHM Semiconductor

RPI-1035 Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for optimal performance of RPI-1035?
  A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output traces short and away from noise sources. Use a common mode choke or ferrite bead to filter the input power.
• How do I ensure the RPI-1035 operates within its specified temperature range?
  Ensure good airflow around the device, use a heat sink if necessary, and avoid blocking the airflow around the device. Monitor the device's temperature using a thermocouple or thermal camera.
• What is the recommended input capacitor value and type for RPI-1035?
  A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for input decoupling. The capacitor should be placed as close to the VIN pin as possible.
• How do I troubleshoot issues with the RPI-1035, such as output voltage instability or overheating?
  Use an oscilloscope to monitor the input and output voltages, and check for any signs of oscillation or noise. Verify the input voltage and current are within the specified range. Check the PCB layout and thermal design for any potential issues.
• Can I use the RPI-1035 in a high-reliability or safety-critical application?
  The RPI-1035 is a commercial-grade device, and its use in high-reliability or safety-critical applications should be carefully evaluated. Consult with ROHM Semiconductor or a qualified engineer to determine the device's suitability for such applications.
