FAN7688SJX Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the thermal path short and use a thermal pad on the bottom of the IC.
  • Ensure good thermal design, use a heat sink if necessary, and follow the recommended operating conditions. Monitor the junction temperature (TJ) and adjust the design accordingly.
  • The maximum allowed voltage on the VIN pin is 28V, but it's recommended to keep it below 24V for reliable operation.
  • Yes, but ensure the PCB is designed to handle high currents, and consider using a heat sink or thermal interface material to maintain a safe junction temperature.
  • Check the input voltage, output voltage, and current. Verify the PCB layout and thermal design. Use an oscilloscope to check for oscillations or noise on the output.
