LTC3890EUH#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the VIN pin is 28V, but it's recommended to keep it below 24V for optimal performance and reliability.
-
To optimize the layout, keep the high-current paths short and wide, use a solid ground plane, and place the input capacitors close to the VIN pin. Also, ensure that the switching node (SW pin) has a low impedance path to the output inductor.
-
The recommended output inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5 ohms or less) is recommended to minimize losses and improve efficiency.
-
The output voltage is set by the resistive divider network connected to the FB pin. The recommended resistors are R1 = 10kohm and R2 = 2.49kohm for a 1.8V output, but you can adjust the values to achieve the desired output voltage.
-
The maximum output current capability of the LTC3890EUH is 2A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
