LT3990EMSE-3.3#PBF 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 the recommended output capacitor value and type, and keep the output voltage within the specified range. Also, avoid using long output traces and keep the output capacitor close to the IC.
  • The minimum input capacitance required is 10uF, but it's recommended to use a 22uF or larger capacitor to ensure stability and optimal performance.
  • The LT3990EMSE-3.3#PBF is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage at high temperatures to prevent overheating and ensure reliability.
  • The 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 IC doesn't overheat.
