LTC3805EMSE#TRPBF Frequently Asked Questions (FAQs)

  • A good PCB layout for the LTC3805EMSE involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces between the IC and the capacitors. A 4-layer PCB with a dedicated power plane and a dedicated ground plane is recommended.
  • The input capacitor should have a low ESR and be rated for the maximum input voltage. The output capacitor should have a low ESR and be rated for the maximum output voltage. A good starting point is to use ceramic capacitors with a capacitance value of 10uF to 22uF for both the input and output.
  • The LTC3805EMSE can operate in an ambient temperature range of -40°C to 125°C. However, the maximum junction temperature should not exceed 150°C.
  • The LTC3805EMSE has a resistive divider network that sets the output voltage. The output voltage can be programmed by selecting the correct values for the resistors R1 and R2. The datasheet provides a formula to calculate the values of R1 and R2 based on the desired output voltage.
  • The maximum output current that the LTC3805EMSE can deliver is 5A. However, the output current should be derated based on the ambient temperature and the input voltage.
