LTC3636IUFD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3636IUFD is 36V, but it's recommended to keep it below 34V to ensure reliable operation.
  • To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and wide. Also, avoid routing sensitive signals near the inductor.
  • The recommended inductor value is 2.2μH to 4.7μH, and a shielded inductor is recommended to reduce EMI. The inductor should have a high saturation current rating and low DC resistance.
  • The output voltage of the LTC3636IUFD can be adjusted by changing the resistor divider ratio of the feedback resistors (R1 and R2). The output voltage is calculated as Vout = 0.8V x (1 + R2/R1).
  • The maximum output current that the LTC3636IUFD can deliver is 3A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature.
