LTC3523EUD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3523EUD is 18V, but it's recommended to keep it below 15V for optimal performance and reliability.
  • To optimize inductor selection, consider the inductor's saturation current, DC resistance, and core loss. A good starting point is to choose an inductor with a saturation current at least 1.5 times the peak current, and a DC resistance less than 100mΩ. Also, consider using a shielded inductor to reduce EMI.
  • To minimize EMI and noise, keep the switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and keep the input and output capacitors close to the IC. Also, use a Kelvin connection for the output voltage sense lines and keep the feedback trace short and direct.
  • The output voltage of the LTC3523EUD can be adjusted by changing the resistor divider ratio (R1 and R2) connected to the FB pin. Use the formula VOUT = 0.8V x (1 + R2/R1) to calculate the desired resistor values.
  • The maximum ambient temperature range for the LTC3523EUD is -40°C to 125°C, but the junction temperature should not exceed 150°C for reliable operation.
