LM3671LC-1.2/NOPB datasheet by Texas Instruments

LM3671LC-1.2/NOPB Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LM3671LC-1.2/NOPB can handle?
  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, keep the output capacitor close to the device to minimize parasitic inductance.
• What is the minimum input capacitance required for the LM3671LC-1.2/NOPB?
  The minimum input capacitance required is 1uF, but it's recommended to use a 4.7uF or larger capacitor to ensure stability and reduce input voltage ripple.
• Can I use the LM3671LC-1.2/NOPB in a high-temperature environment?
  The device is rated for operation up to 125°C, but the junction temperature should be kept below 150°C to ensure reliability and prevent thermal shutdown.
• How do I calculate the output voltage of the LM3671LC-1.2/NOPB?
  The output voltage is fixed at 1.2V, but it can be adjusted using an external resistor divider network. The formula to calculate the output voltage is: Vout = 1.2V * (1 + R1/R2), where R1 and R2 are the resistors in the divider network.
