LT3645IMSE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT3645 can handle is 40V, but it's recommended to keep it below 36V for reliable operation.
  • To ensure the stability of the output voltage, make sure to use the recommended output capacitor values and types, and follow the layout guidelines provided in the datasheet.
  • The minimum input voltage required for the LT3645 to operate is 3.5V, but it's recommended to keep it above 4V for reliable startup.
  • Yes, the LT3645 is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Make sure to follow the thermal management guidelines in the datasheet.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESL) / (Cout * fsw), where ESL is the equivalent series inductance of the output capacitor, Cout is the output capacitance, and fsw is the switching frequency.
