LTC3548IDD#PBF Frequently Asked Questions (FAQ)
-
The maximum input voltage that can be applied to the LTC3548 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal regulator.
-
To minimize noise and EMI, 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, avoid routing high-frequency signals near the IC and use shielding if possible.
-
The recommended input capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor such as X5R or X7R. The capacitor should be placed as close as possible to the VIN pin.
-
The output voltage of the LTC3548 can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The output voltage range is from 0.8V to 5V.
-
The maximum output current that the LTC3548 can deliver is 2A, but it's recommended to keep it below 1.5A for optimal performance and to prevent overheating.
