FAN48685UC08X Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the switching node (SW) away from sensitive analog nodes and ensure good thermal conduction to the heat sink.
  • Use the provided compensation network values as a starting point and adjust based on the specific application's requirements. Consider the output capacitor's ESR, inductor's DCR, and the desired transient response.
  • The maximum allowed input voltage ripple is 10% of the nominal input voltage. Exceeding this may affect the converter's stability and efficiency.
  • Yes, but ensure the inductor's saturation current, DCR, and core material are suitable for the application. Consult the inductor manufacturer's datasheet and perform thorough testing to ensure compatibility.
  • Ensure the sense resistor (Rs) is correctly sized and connected. The OCP threshold is 1.5x the nominal output current. Verify the OCP response time and threshold in your specific application.
