LT3952AEFE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT3952AEFE can handle is 40V, but it's recommended to operate it within the specified input voltage range of 7V to 36V for optimal performance.
  • To ensure the stability of the output voltage, it's essential to use the recommended output capacitor value and type, and to follow the layout guidelines provided in the datasheet to minimize noise and oscillations.
  • The maximum output current that the LT3952AEFE can deliver is 2A, but it's recommended to operate it within the specified output current range of 0A to 1.5A for optimal performance and reliability.
  • The output voltage of the LT3952AEFE can be programmed using an external resistor divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
  • The EN (enable) pin 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 and enters a low-power shutdown mode.
