ACZRA4733-HF 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 traces as short as possible and use a common mode choke to reduce EMI.
  • Ensure good airflow around the device, use a heat sink if necessary, and avoid blocking the airflow vents on the device. Monitor the device temperature using the thermal monitoring pin (TMON).
  • A 10uF to 22uF X7R or X5R ceramic capacitor is recommended for the input filter. The capacitor should be placed as close to the VIN pin as possible.
  • Check the input voltage, output voltage, and enable pin (EN) for proper operation. Verify the PCB layout and component placement. Use an oscilloscope to check for voltage ripple, noise, and oscillations.
  • The maximum allowed voltage on the output pin is 5.5V. Exceeding this voltage may damage the device.
