LM2678SD-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V 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.
  • The maximum output current is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
  • The output voltage is fixed at 5.0V, but you can adjust it by using an external resistor divider network, following the datasheet's guidelines.
  • The thermal shutdown temperature is typically 150°C, and the device will automatically shut down to prevent damage.
