LTC3637HMSE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3637 is 40V, but it's recommended to keep it below 36V for reliable operation.
  • To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-frequency switching nodes (e.g., SW and VIN) away from sensitive analog nodes. Also, use a shielded inductor and orient it to minimize radiation.
  • The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5Ω to 1.5Ω) is recommended. The inductor type should be a high-frequency, low-loss inductor with a high saturation current rating.
  • The output voltage of the LTC3637 is set by the resistive divider network connected to the FB pin. The output voltage is calculated as VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The maximum output current that the LTC3637 can deliver is 3A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
