LTC1771ES8#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC1771ES8 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal components.
-
To ensure stability, make sure to follow the recommended layout and component placement guidelines, use a low-ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VCC and GND pins to filter out high-frequency noise.
-
The minimum ESR required for the output capacitor is 0.05Ω, but it's recommended to use a capacitor with an ESR of 0.01Ω or lower to ensure optimal performance and stability.
-
The LTC1771ES8 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage according to the temperature derating curve provided in the datasheet to ensure reliable operation.
-
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.
