LT3971AIMSE-5#PBF Frequently Asked Questions (FAQ)
-
The LT3971 can handle input voltages up to 60V, but it's recommended to keep the input voltage below 50V for optimal performance and reliability.
-
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and use a sufficient output capacitor with a low ESR (Equivalent Series Resistance).
-
The minimum input voltage required for the LT3971 to operate is 4.5V, but it's recommended to keep the input voltage above 5V for optimal performance.
-
The LT3971 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliability and prevent overheating.
-
The output voltage ripple can be calculated using the formula: ΔVout = (Iout * ESR) / (fsw * Cout), where Iout is the output current, ESR is the output capacitor's equivalent series resistance, fsw is the switching frequency, and Cout is the output capacitance.
