LM3670MF-1.2/NOPB Frequently Asked Questions (FAQs)

  • The maximum input voltage is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent overheating.
  • 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.
  • 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.
  • 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.
  • Power dissipation can be calculated using the formula: Pd = (Vin - Vout) x Iout. Make sure to consider the thermal resistance and junction temperature to ensure the device operates within its thermal limits.
