LM2673SX-12/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 30V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 22uF, and ensure the ESR (Equivalent Series Resistance) is less than 1 ohm. Also, use a low-ESR capacitor for the input filter capacitor.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • Use a heat sink with a thermal resistance of less than 10°C/W, and ensure good airflow around the device. Also, keep the junction temperature below 125°C.
  • The device is rated for operation up to 125°C, but the output voltage may decrease at high temperatures. Use a heat sink and ensure good airflow to prevent overheating.
