LTC1778EGN-1 Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC1778EGN-1 is 36V, but it's recommended to keep it below 30V for reliable operation.
-
To ensure stability, make sure to follow the recommended layout and component selection guidelines in the datasheet, and add a 10nF to 100nF capacitor between the VCC and GND pins to filter out 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 for optimal performance.
-
The LTC1778EGN-1 is rated for operation up to 125°C, but it's recommended to derate the output current and voltage at high temperatures to ensure reliable operation.
-
You can synchronize the switching frequency of multiple LTC1778EGN-1 devices by connecting the SYNC pin of each device to a common clock signal, and ensuring that the devices are properly phased to avoid beat frequencies.
