AL1793AFE-13 Frequently Asked Questions (FAQs)

  • A thermal pad is recommended to be connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.
  • Ensure that the input voltage is within the recommended range, and the output capacitor is of sufficient value (at least 10uF) and low ESR. Also, ensure that the feedback pin is properly connected to the output voltage.
  • The maximum ambient temperature for reliable operation is 85°C, but it's recommended to keep it below 70°C for optimal performance and reliability.
  • Yes, but ensure that the device is properly secured to the PCB and the PCB is securely fastened to the system. Also, consider using a vibration-resistant capacitor for the output capacitor.
  • Use a voltage supervisor or a reset IC to monitor the input voltage and reset the system if it goes out of range. Also, consider adding overvoltage protection (OVP) and undervoltage protection (UVP) circuits.
