LM5169FDDAR Frequently Asked Questions (FAQs)

  • The LM5169FDDAR can handle input voltages up to 65V, but it's recommended to keep it below 60V for reliable operation.
  • Make sure to provide adequate heat sinking, keep the device away from heat sources, and ensure good airflow around the device. Also, monitor the junction temperature (TJ) and adjust the operating conditions accordingly.
  • Use a 4-layer PCB with a solid ground plane, keep the input and output capacitors close to the device, and use short, wide traces for the high-current paths. Refer to the TI application note SLUA623 for more details.
  • Choose capacitors with a voltage rating higher than the maximum input voltage, and an ESR (Equivalent Series Resistance) that meets the device's requirements. X5R or X7R ceramic capacitors are recommended for the output capacitor.
  • The minimum input capacitance required is 10uF, but it's recommended to use a higher value (e.g., 22uF) to ensure stable operation.
