LTC3374HUHF#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3374HUHF is 36V, but it's recommended to keep it below 34V 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 1.5μH and 3.3μH, 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 can be set using the FB pin and a resistive divider. The FB pin is regulated to 0.8V, so the output voltage is determined by the ratio of the resistors in the divider. For example, for a 3.3V output, use a 1kΩ resistor from VOUT to FB and a 2.2kΩ resistor from FB to GND.
  • The maximum output current that the LTC3374HUHF can deliver is 4A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
