LM3478MAX/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3478MAX/NOPB is 18V. Exceeding this voltage may damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled from the input voltage using a capacitor with a value of at least 1uF.
  • The maximum output current that the LM3478MAX/NOPB can deliver is 500mA. Exceeding this current may cause the device to overheat or fail.
  • To protect the LM3478MAX/NOPB from overheating, it is recommended to provide adequate heat sinking, such as a thermal pad or a heat sink, and to ensure good airflow around the device. Additionally, the device should be operated within its recommended operating temperature range of -40°C to 125°C.
  • Yes, the LM3478MAX/NOPB can be used in high-temperature applications up to 125°C. However, the device's performance and reliability may be affected at high temperatures, and the user should consult the datasheet and application notes for guidance on high-temperature operation.
