LTC3880EUJ-1#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, 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 analog nodes.
  • The recommended operating frequency range for the LTC3880EUJ-1#PBF is between 200 kHz to 400 kHz. Operating outside this range may affect the converter's efficiency and stability.
  • The inductor value depends on the input voltage, output voltage, and desired output current. A good starting point is to use the inductor value recommended in the datasheet (e.g., 1.5 μH). Then, adjust the value based on the specific application requirements and efficiency targets.
  • The SYNC/MODE pin allows synchronization of multiple LTC3880EUJ-1#PBF devices or external clock sources. To use it, connect the SYNC/MODE pin to an external clock source or another LTC3880EUJ-1#PBF device, and set the frequency to the desired value (e.g., 300 kHz).
