LT8390HFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT8390HFE#PBF can handle is 60V, but it's recommended to operate within the specified input voltage range of 4.5V to 40V for optimal performance.
  • To ensure the stability of the output voltage, make sure to follow the recommended layout and component selection guidelines in the datasheet, and use a sufficient output capacitor with a low ESR (Equivalent Series Resistance) value.
  • The maximum output current that the LT8390HFE#PBF can deliver is 2A, but it's recommended to operate within the specified output current range of 0A to 1.5A for optimal performance and reliability.
  • The output voltage of the LT8390HFE#PBF can be programmed using an external resistor divider network connected to the FB (Feedback) pin. The output voltage can be calculated using the formula: VOUT = 0.8V x (R1 + R2) / R2, where R1 and R2 are the resistors in the divider network.
  • The EN (Enable) pin on the LT8390HFE#PBF 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 when not in use.
