LTC3555EUFD#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal regulator.
-
To minimize EMI and noise, 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 analog nodes.
-
A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended for the input capacitor. X5R or X7R dielectric types are suitable for most applications.
-
The inductor value and type depend on the output voltage, output current, and switching frequency. A shielded inductor with a value between 1uH to 10uH is recommended. The inductor should have a high saturation current rating and low DC resistance.
-
The SYNC pin allows the LTC3555EUFD#PBF to synchronize its switching frequency with an external clock signal. This can be useful in noise-sensitive applications or when multiple converters need to be synchronized. To use the SYNC pin, connect it to an external clock signal with a frequency between 300kHz to 2.5MHz.
