LTC3614EUDD#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3614EUDD is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
  • To minimize EMI and noise, it's recommended to follow a star-ground configuration, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive nodes.
  • The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor is recommended to reduce EMI. The inductor type should be a low-loss, high-current inductor with a high saturation current rating.
  • The output voltage of the LTC3614EUDD can be adjusted by changing the resistor divider ratio of the feedback resistors (RFB1 and RFB2). The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + RFB2/RFB1).
  • The maximum output current that the LTC3614EUDD 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.
