EN5322QI Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power paths.
  • Use the EN5322QI's built-in compensation network or use the datasheet's guidelines to design a custom compensation network based on your specific output capacitor and inductor values.
  • The maximum input voltage is 6.5V, but it's recommended to keep the input voltage below 5.5V for optimal performance and reliability.
  • The EN5322QI is rated for operation up to 125°C, but thermal derating may be necessary for high-temperature applications. Consult the datasheet for thermal derating guidelines.
  • Use a shielded inductor, keep the switching node (SW) away from sensitive circuits, and use a common-mode choke or ferrite bead to reduce EMI emissions.
