LM3671MF-1.8 Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LM3671MF-1.8 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the input and output capacitors close to the device to minimize noise and oscillations.
  • The minimum input voltage required for the LM3671MF-1.8 to operate is 2.7V, but it's recommended to keep it above 3V for optimal performance and to ensure that the output voltage is within the specified range.
  • The LM3671MF-1.8 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage to ensure reliable operation at high temperatures. Consult the datasheet for more information on thermal derating.
  • The power dissipation of the LM3671MF-1.8 can be calculated using the formula: Pd = (Vin - Vout) x Iout + (Vin x Iq), where Vin is the input voltage, Vout is the output voltage, Iout is the output current, and Iq is the quiescent current.
