LT3845MPFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT3845 can handle is 42V, but it's recommended to keep it below 36V for reliable operation.
  • To ensure the stability of the output voltage, make sure to use the recommended output capacitor value and type, and also ensure that the input capacitor is properly sized and placed close to the IC.
  • The maximum output current that the LT3845 can deliver is 3.5A, but it's recommended to keep it below 3A for reliable operation and to prevent overheating.
  • The output voltage can be adjusted by changing the resistor divider ratio between the FB pin and the output voltage. A higher resistor value will result in a higher output voltage, and vice versa.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is pulled low, the regulator is disabled, and when it's pulled high, the regulator is enabled.
