LM5085QMY/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 60V, but it's recommended to keep it below 50V for reliable operation.
  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR capacitor for the input filter capacitor.
  • The maximum output current is 5A, but it's recommended to keep it below 4A for reliable operation and to prevent overheating.
  • You can use an external current sense resistor and a comparator to detect overcurrent conditions and shut down the device. Alternatively, you can use a fuse or a PTC resettable fuse.
  • The thermal shutdown temperature is typically around 150°C, but it can vary depending on the specific device and operating conditions.
