LM2576T-ADJ/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM2576T-ADJ/NOPB is 40V. Exceeding this voltage can cause damage to the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 22uF with an ESR of 0.05 ohms or less, and to place the output capacitor close to the output pin of the device.
  • The minimum input voltage required for the LM2576T-ADJ/NOPB to operate is 7V. However, the device can operate with input voltages as low as 4V, but with reduced performance.
  • The output voltage of the LM2576T-ADJ/NOPB can be adjusted by using a resistive divider network between the output pin and the adjust pin. The output voltage is determined by the ratio of the resistors in the divider network.
  • The maximum output current that the LM2576T-ADJ/NOPB can deliver is 3A. However, the output current should be derated for high temperatures and high input voltages.
