LT3690EUFE#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that the LT3690EUFE can handle is 40V, but it's recommended to keep it below 36V for reliable operation.
-
To minimize EMI, keep the input and output capacitors close to the IC, use a solid ground plane, and keep the high-current paths short and wide. Also, avoid routing sensitive signals near the inductor.
-
The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., Coilcraft XAL series) is recommended to minimize radiated emissions.
-
The output voltage can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. Use the formula in the datasheet to calculate the required resistor values.
-
The maximum output current that the LT3690EUFE can deliver is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature.
