LT3825EFE#TRPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3825EFE is 60V, but it's recommended to operate within the specified input voltage range of 4.5V to 38V for optimal performance.
  • To ensure the stability of the output voltage, it's essential to follow the recommended layout and component selection guidelines, including the use of a suitable output capacitor and a low-ESR input capacitor. Additionally, the output voltage should be decoupled with a capacitor to prevent oscillations.
  • The maximum output current that the LT3825EFE can deliver is 5A, but it's recommended to operate within the specified output current range of 0A to 3A for optimal performance and to prevent overheating.
  • The output voltage of the LT3825EFE can be programmed using the FB (feedback) pin and an external resistor divider network. The output voltage is determined by the ratio of the resistors in the divider network and the internal reference voltage of 0.8V.
  • The EN (enable) pin on the LT3825EFE is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled. This pin can be used to implement power sequencing or to shut down the regulator during standby modes.
