LM5161PWPT Frequently Asked Questions (FAQs)

  • The LM5161PWPT 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 power paths. Avoid routing sensitive signals near the device's switching nodes.
  • Use the EN pin to disable the device when not in use, minimize the input voltage, and optimize the output voltage and current to reduce power consumption. Also, consider using the device's low-power modes (e.g., pulse-skipping mode).
  • Use a common-mode choke and a differential-mode filter to reduce EMI emissions. Place the filter components close to the device, and ensure the filter's impedance is matched to the device's output impedance.
