LTC3805IMSE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LTC3805 can handle is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • The compensation network for the LTC3805 requires careful tuning to ensure stability. A good starting point is to use the values recommended in the datasheet, and then adjust them based on the specific application and layout. It's also important to consider the output capacitor's ESR and the inductor's DCR when designing the compensation network.
  • The minimum input voltage required for the LTC3805 to operate is 3.5V, but it's recommended to keep it above 4V for optimal performance and reliability.
  • The LTC3805 is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as the temperature increases to ensure reliability. It's also important to consider the thermal design and layout of the PCB to ensure adequate heat dissipation.
  • To ensure the LTC3805 is stable and doesn't oscillate, it's important to follow the layout and compensation guidelines in the datasheet, and to use a sufficient output capacitor with a low ESR. It's also important to minimize the loop area and keep the feedback traces short and direct.
