LM3671QMF-1.2/NOPB datasheet by Texas Instruments

LM3671QMF-1.2/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LM3671QMF-1.2/NOPB?
  The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the device.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a 1uF or larger input capacitor to filter out noise and ripple.
• What is the minimum input voltage required for the LM3671QMF-1.2/NOPB to operate?
  The minimum input voltage is 2.7V, but it's recommended to keep it above 3V for optimal performance and to ensure the output voltage remains stable.
• Can I use the LM3671QMF-1.2/NOPB in a high-temperature environment?
  The device is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to prevent overheating and ensure reliability.
• How do I calculate the output voltage of the LM3671QMF-1.2/NOPB?
  The output voltage is set by the resistor divider network connected to the FB pin. Use the formula: Vout = 1.2V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
