LTC3873ETS8-5#TRMPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LTC3873 can handle is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
-
The compensation network for the LTC3873 requires careful design to ensure stability. A good starting point is to use the recommended values in the datasheet, and then adjust them based on the specific application and PCB layout.
-
The minimum input capacitance required for the LTC3873 is 10uF, but it's recommended to use a higher value (e.g. 22uF) to ensure stability and reduce input voltage ripple.
-
The LTC3873 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.
-
To synchronize the switching frequency of multiple LTC3873 devices, connect the SYNC pin of each device to a common clock signal, and ensure that the clock frequency is within the recommended range of 250kHz to 400kHz.
