LTC3458LEDE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • 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., LX) 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., 0.1Ω) is recommended. The inductor type should be a high-frequency, low-loss inductor with a high saturation current rating.
  • The output voltage 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 LTC3458LEDE#PBF 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.
