LT3504EUFD#TRPBF Frequently Asked Questions (FAQ)

  • The maximum input voltage that can be applied to the LT3504EUFD is 36V, but it's recommended to keep it below 34V for reliable operation.

  • To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the output filter capacitor.

  • The maximum output current that the LT3504EUFD can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation and to prevent overheating.

  • The output voltage of the LT3504EUFD can be adjusted by using a resistive divider network between the output and the feedback pin. The ratio of the resistors determines the output voltage.

  • The thermal shutdown temperature of the LT3504EUFD is 150°C. If the junction temperature exceeds this value, the device will shut down to prevent damage.
