FAN9673Q Frequently Asked Questions (FAQs)

  • A good PCB layout for the FAN9673Q involves keeping the input and output capacitors close to the device, using a solid ground plane, and minimizing the length of the traces to reduce parasitic inductance. A 4-layer PCB with a dedicated power plane and a solid ground plane is recommended.
  • The input capacitor should have a low ESR and be rated for the input voltage. A ceramic capacitor with an X7R or X5R dielectric is recommended. The output capacitor should have a low ESR and be rated for the output voltage. A ceramic capacitor with an X7R or X5R dielectric is recommended. The capacitance value should be chosen based on the output voltage and the desired ripple voltage.
  • The FAN9673Q is rated for an ambient temperature range of -40°C to 125°C. However, the device may not operate within specifications at the extreme temperatures. It is recommended to derate the device's performance at high temperatures.
  • To ensure stability, the FAN9673Q requires a minimum output capacitance of 10uF. The output capacitor should be placed close to the device and the traces should be kept short to minimize parasitic inductance. Additionally, the input voltage should be well-regulated and the device should be operated within its specified input voltage range.
  • The maximum input voltage for the FAN9673Q is 28V. Exceeding this voltage may damage the device. It is recommended to use a voltage regulator or a voltage limiter to ensure the input voltage does not exceed the maximum rating.
