LM3407MY/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 42V, but it's recommended to keep it below 40V for reliable operation.
  • To ensure stability, use a minimum output capacitance of 10uF, 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 1.5A, but it's recommended to keep it below 1.2A for reliable operation and to prevent overheating.
  • To reduce noise and ripple, use a low-ESR output capacitor, and consider adding a noise-reducing capacitor (e.g., 10nF) between the output and ground. Also, ensure good PCB layout and decoupling.
  • The thermal shutdown temperature is typically around 150°C, but it can vary depending on the specific device and operating conditions.
