LM3466MRX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V 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 design accordingly.
  • A 10uF to 22uF ceramic or electrolytic capacitor with a voltage rating of 50V or higher is recommended. The capacitor should be placed as close to the VIN pin as possible.
  • Use a low-ESR output capacitor (e.g., ceramic or polymer capacitors), minimize the output capacitor's equivalent series resistance (ESR), and ensure the output capacitor is properly decoupled from the output voltage.
  • The minimum input voltage is 7V, but it's recommended to keep it above 8V for reliable operation.
