LTC3775EMSE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LTC3775 is 60V, but it's recommended to keep it below 50V for reliable operation.
  • To minimize EMI, it's recommended to keep the switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and keep the input and output capacitors close to the IC. Additionally, use a shielded inductor and orient it to minimize radiation.
  • The recommended operating frequency range for the LTC3775 is between 100kHz to 500kHz. Operating outside this range may affect the converter's efficiency and stability.
  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value recommended in the datasheet, and then adjust it based on the specific application requirements. It's also recommended to use an inductor with a high saturation current rating and low DC resistance.
  • The maximum output current that the LTC3775 can deliver is 5A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
