LT8611IUDD#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LT8611IUDD is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
-
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) away from sensitive 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 this application.
-
The inductor value depends on the output voltage, output current, and switching frequency. A shielded inductor with a value between 1.5uH to 3.3uH is recommended. The inductor type should be a low-loss, high-current inductor with a high saturation current rating.
-
The thermal derating curve for the LT8611IUDD is not explicitly stated in the datasheet, but it can be estimated based on the junction-to-ambient thermal resistance (RθJA) of 45°C/W. A derating of 1.5%/°C above 25°C is a reasonable estimate.
