LM3424MHX/NOPB datasheet by Texas Instruments

LM3424MHX/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3424MHX/NOPB?
  The maximum input voltage that can be applied to the LM3424MHX/NOPB is 42V, but it's recommended to keep it below 40V for reliable operation.
• How do I ensure the stability of the output voltage in the LM3424MHX/NOPB?
  To ensure stability, it's essential to use a minimum output capacitance of 10uF with an ESR of 1 ohm or less, and to keep the output voltage within the recommended range of 1.2V to 15V.
• What is the maximum output current that the LM3424MHX/NOPB can deliver?
  The maximum output current that the LM3424MHX/NOPB can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.
• How do I choose the correct inductor value for the LM3424MHX/NOPB?
  The inductor value should be chosen based on the output voltage, output current, and switching frequency. A general rule of thumb is to use an inductor with a value between 1uH and 10uH, and to consult the datasheet for specific recommendations.
• What is the purpose of the EN pin on the LM3424MHX/NOPB?
  The EN (Enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
