LTC3803ES6#PBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that the LTC3803ES6 can handle is 36V, but it's recommended to keep it below 30V for reliable operation.

  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value based on the switching frequency and output voltage. A good starting point is to use an inductor with an inductance value between 1uH to 10uH.

  • The SYNC pin is used to synchronize the switching frequency of the LTC3803ES6 with an external clock signal. This can be useful in noise-sensitive applications where it's desirable to synchronize the switching frequency with other system clocks.

  • The output voltage of the LTC3803ES6 can be adjusted by changing the ratio of the resistors R1 and R2 connected to the FB pin. The output voltage is determined by the formula Vout = 0.8V x (1 + R2/R1).

  • The maximum output current that the LTC3803ES6 can deliver is 3A, but it's recommended to derate the output current based on the ambient temperature and the input voltage to ensure reliable operation.
