The maximum input voltage that can be applied to the LTC3605 is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal components.
To optimize the layout of the LTC3605, it's recommended to follow the layout guidelines provided in the datasheet, including keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing the length of the traces.
The recommended input capacitor value for the LTC3605 is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor, such as an X5R or X7R type, to minimize the equivalent series resistance and ensure stable operation.
The output voltage of the LTC3605 can be adjusted by changing the value of the feedback resistors, R1 and R2, according to the formula provided in the datasheet. The output voltage can be set to any value between 2.5V and 5.5V.
The maximum output current that the LTC3605 can deliver is 1.5A, but it's recommended to keep the output current below 1A for optimal performance and to prevent overheating.
