LT3470AEDDB#TRMPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3470AEDDB is 15V, but it's recommended to operate within the specified input voltage range of 2.5V to 12V for optimal performance.
  • To ensure stability, 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 input voltage should be well-regulated and free of noise.
  • The maximum output current that the LT3470AEDDB can deliver is 700mA. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
  • The output voltage of the LT3470AEDDB can be configured by selecting the appropriate resistive divider ratio using 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 low, the regulator is disabled, and the output voltage is turned off. This pin can be used to implement power sequencing or to turn off the regulator during shutdown or standby modes.
