LM22673MR-5.0/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM22673MR-5.0/NOPB is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure stability, it's essential to use the recommended output capacitor value and type, and to place it as close to the output pin as possible. Additionally, the input capacitor should be a low-ESR type, and the PCB layout should be designed to minimize noise and parasitic inductance.
  • The maximum output current that the LM22673MR-5.0/NOPB can deliver is 3A, but it's recommended to keep it below 2.5A for optimal performance and reliability.
  • The output voltage of the LM22673MR-5.0/NOPB can be calculated using the formula: Vout = (R1 / R2) * 1.25V, where R1 and R2 are the resistors connected to the FB pin.
  • The EN (Enable) pin is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled.
