LTC3411AEMS#TRPBF datasheet by Linear Technology

LTC3411AEMS#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3411AEMS can handle?
  The maximum input voltage that the LTC3411AEMS can handle is 36V, but it's recommended to keep it below 34V for reliable operation.
• How do I optimize the layout for the LTC3411AEMS to minimize EMI?
  To minimize EMI, it's recommended to keep the input and output capacitors close to the IC, use a solid ground plane, and keep the switching node (SW pin) away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
• What is the recommended inductor value and type for the LTC3411AEMS?
  The recommended inductor value is between 1.5uH to 3.3uH, and it's recommended to use a shielded inductor with a low DCR (DC resistance) to minimize losses. A good option is the Würth Elektronik 744778100 or similar.
• How do I set the output voltage of the LTC3411AEMS?
  The output voltage of the LTC3411AEMS is set by the resistive divider network connected to the FB pin. The formula to calculate the output voltage is Vout = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
• What is the maximum output current that the LTC3411AEMS can deliver?
  The maximum output current that the LTC3411AEMS can deliver is 1.5A, but it's recommended to derate the output current based on the input voltage and ambient temperature to ensure reliable operation.
