LM2671MX-ADJ/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM2671MX-ADJ/NOPB is 40V. Exceeding this voltage can cause damage to the device.

  • To ensure stability of the output voltage, it is recommended to use a minimum output capacitance of 22uF and an ESR of less than 1 ohm. Additionally, the output voltage should be decoupled with a 10uF capacitor.

  • The minimum input voltage required for the LM2671MX-ADJ/NOPB to operate is 7.5V. However, the device can operate down to 7V with a reduced output current capability.

  • The LM2671MX-ADJ/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may be affected at high temperatures. It is recommended to derate the output current and input voltage at high temperatures.

  • The output voltage of the LM2671MX-ADJ/NOPB can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The output voltage can be calculated using the formula: Vout = 1.245V x (1 + R1/R2).
