LTC3805IDD#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3805 is 28V, but it's recommended to keep it below 24V for reliable operation.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet, and then adjust it based on the specific requirements of your design.
  • The maximum output current that the LTC3805 can deliver is 5A, but it's limited by the thermal performance of the package and the PCB design.
  • To minimize EMI and noise, it's recommended to follow good PCB layout practices, such as keeping the switching node (SW) away from sensitive analog nodes, using a solid ground plane, and minimizing the loop area of the switching current path.
  • The LTC3805 is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It's recommended to derate the output current and ensure good thermal design to prevent overheating.
