LTC3890EUH#PBF Frequently Asked Questions (FAQ)
-
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 keep the switching node (SW pin) away from sensitive analog nodes, use a solid ground plane, and keep the high-current paths short and wide. Additionally, use a common-mode choke and a shielded inductor to reduce radiated emissions.
-
The recommended operating frequency range for the LTC3890EUH#PBF is between 100kHz to 500kHz. Operating outside this range may affect the converter's efficiency and stability.
-
To select the right inductor, consider the maximum current rating, inductance value, and core material. A good starting point is to choose an inductor with a saturation current rating of at least 1.5 times the maximum output current, and an inductance value between 1uH to 10uH.
-
The SYNC pin allows the LTC3890EUH#PBF to synchronize with an external clock signal. This can be useful in multi-phase or multi-converter systems. To use the SYNC pin, connect it to an external clock signal with a frequency between 100kHz to 500kHz, and ensure the clock signal is clean and stable.
