LTC3426ES6#TRMPBF datasheet by Linear Technology

LTC3426ES6#TRMPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LTC3426 can handle?
  The maximum input voltage that the LTC3426 can handle is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
• How do I optimize the inductor selection for the LTC3426?
  To optimize the inductor selection, consider the inductor's saturation current, DC resistance, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and a DC resistance of less than 100mΩ.
• What is the recommended PCB layout for the LTC3426?
  For optimal performance, keep the input and output capacitors close to the IC, and use a solid ground plane to reduce noise and EMI. Keep the switching node (SW pin) away from sensitive analog nodes, and use a Kelvin connection for the output voltage sense lines.
• How do I adjust the output voltage of the LTC3426?
  The output voltage of the LTC3426 can be adjusted by changing the resistor divider ratio on the FB pin. Use the formula Vout = 0.8V x (R1 + R2) / R2 to calculate the desired resistor values.
• What is the maximum output current that the LTC3426 can deliver?
  The maximum output current that the LTC3426 can deliver is 2A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
