LTC3374AIFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3374AIFE is 15V, but it's recommended to keep it below 12V 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 for the LTC3374AIFE is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (DC resistance) is recommended. The inductor type should be able to handle the peak current and have a high saturation current rating.
  • The LTC3374AIFE output voltage can be configured by selecting the appropriate resistors for the feedback network (RFBT and RFB). The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The maximum output current that the LTC3374AIFE can deliver is 4A per channel, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
