LM2678SX-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2678SX-5.0/NOPB is 15V. 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 22uF and an ESR of 0.05 ohms or less. Additionally, the input capacitor should be at least 10uF with an ESR of 0.1 ohms or less.
  • The maximum output current that the LM2678SX-5.0/NOPB can provide is 3A. Exceeding this current may cause the device to overheat or shut down.
  • The output voltage of the LM2678SX-5.0/NOPB can be calculated using the formula: Vout = 5.0V (fixed output voltage). The output voltage is fixed at 5.0V and cannot be adjusted.
  • The operating temperature range of the LM2678SX-5.0/NOPB is -40°C to 125°C. Operating the device outside of this range may affect its performance and reliability.
