LM22673MRX-ADJ/NOPB Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LM22673MRX-ADJ/NOPB is 42V. Exceeding this voltage may damage the device.

  • The output voltage of the LM22673MRX-ADJ/NOPB can be adjusted by connecting a resistor divider network between the output and the ADJ pin. The ratio of the resistors determines the output voltage.

  • The minimum input capacitance required for the LM22673MRX-ADJ/NOPB is 10uF. However, it is recommended to use a higher capacitance value, such as 22uF or 47uF, to ensure stable operation.

  • The LM22673MRX-ADJ/NOPB is rated for operation up to 125°C. However, the device's performance and reliability may degrade at high temperatures. It is recommended to derate the device's output current and voltage at high temperatures.

  • The LM22673MRX-ADJ/NOPB has a built-in overcurrent protection feature that limits the output current to 3.5A. However, it is recommended to add external overcurrent protection, such as a fuse or a current-sensing resistor, to protect the device and the system from overcurrent conditions.
