LTC3548EDD#TRPBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3548EDD is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal regulator.
-
To minimize EMI and noise, it's recommended to follow a star-ground configuration, keep the input and output capacitors close to the IC, and use a solid ground plane. Additionally, use a shielded inductor and keep the switching node (SW) away from sensitive analog nodes.
-
The recommended inductor value is between 1.5uH to 3.3uH, and a shielded inductor with a low DCR (e.g., 0.5Ω) is recommended to minimize losses and EMI. A ferrite core inductor is a good option.
-
The output voltage of the LTC3548EDD can be adjusted by changing the resistive divider ratio (R1 and R2) connected to the FB pin. The output voltage is calculated using the formula: Vout = 0.8V x (1 + R2/R1).
-
The maximum output current that the LTC3548EDD can deliver 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.
