LM2673S-ADJ Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2673S-ADJ is 40V. Exceeding this voltage can cause damage to the device.
  • The output voltage of the LM2673S-ADJ can be adjusted by connecting a resistor divider network between the output and the adjust pin. The ratio of the resistors determines the output voltage.
  • The minimum input voltage required for the LM2673S-ADJ to operate is 7.5V. The device will not regulate the output voltage if the input voltage is below this threshold.
  • The LM2673S-ADJ is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It's recommended to derate the device's power dissipation and output current at high temperatures.
  • To ensure the stability of the LM2673S-ADJ output voltage, it's recommended to use a minimum output capacitance of 22µF and a maximum ESR of 1Ω. Additionally, the input capacitor should be at least 10µF with an ESR of 0.1Ω or less.
