LTC3769HUF#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 40V, but it's recommended to keep it below 38V for reliable operation.
  • To minimize EMI, 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 pin) away from sensitive nodes.
  • The recommended operating frequency range for the LTC3769HUF#PBF is between 100kHz to 1MHz. 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 (e.g., 1.5μH for a 12V input and 5V output). Then, adjust the value based on the specific requirements of your application.
  • The maximum output current that the LTC3769HUF#PBF can deliver is 2A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
