LTC3634EFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3634EFE is 36V, but it's recommended to keep it below 34V to ensure reliable operation.
  • 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 high-frequency switching nodes (e.g. SW pin) away from sensitive analog nodes. Additionally, use a shielded inductor and orient it to minimize radiation.
  • The recommended inductor value is between 1.5uH to 3.3uH, and it's recommended to use a shielded inductor with a high saturation current rating (e.g. > 2A) to minimize core losses and ensure reliable operation.
  • The output voltage of the LTC3634EFE can be adjusted by changing the resistive divider ratio between the VOUT pin and the GND pin. The output voltage is determined by the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider.
  • The maximum output current that the LTC3634EFE can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
