LM2673T-ADJ/NOPB datasheet by Texas Instruments

LM2673T-ADJ/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM2673T-ADJ/NOPB can handle?
  The maximum input voltage is 40V, but it's recommended to keep it below 30V for reliable operation.
• How do I adjust the output voltage of the LM2673T-ADJ/NOPB?
  The output voltage can be adjusted by connecting a resistor divider network between the output and the adjust pin. The datasheet provides a formula to calculate the required resistor values.
• What is the minimum input voltage required for the LM2673T-ADJ/NOPB to operate?
  The minimum input voltage is 7.5V, but it's recommended to keep it above 8V for reliable operation.
• Can I use the LM2673T-ADJ/NOPB in a high-temperature environment?
  The LM2673T-ADJ/NOPB is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Thermal management is crucial in high-temperature environments.
• How do I ensure the stability of the LM2673T-ADJ/NOPB output voltage?
  To ensure stability, a minimum output capacitance of 22µF is recommended, and the ESR (Equivalent Series Resistance) should be less than 1Ω. Additionally, a 10nF capacitor between the adjust pin and ground can help improve stability.
