LTC3890HUH#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the VIN pin is 60V, but it's recommended to keep it below 50V for reliable operation.

  • To ensure stability, make sure to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor. Also, ensure that the feedback resistors are properly selected and placed close to the IC.

  • Yes, the LTC3890HUH#PBF is rated for operation up to 125°C, but it's essential to follow the recommended thermal design and layout guidelines to ensure reliable operation. Additionally, consider the derating of the output current and voltage at high temperatures.

  • To synchronize the switching frequency, connect the SYNC pin of each device to a common clock signal. This ensures that all devices switch at the same frequency, reducing EMI and noise.

  • Follow a star-grounding layout, keeping the high-current paths short and away from sensitive analog signals. Use a solid ground plane, and place the input and output capacitors close to the IC. Also, consider using a shielded inductor and a common-mode choke to reduce EMI.
