LT3470HDDB#TRMPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3470 is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure the stability of the output voltage, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, use a low-ESR ceramic capacitor for the output filter capacitor.
  • The maximum output current that the LT3470 can deliver is 700mA per channel, but it's recommended to keep it below 500mA per channel for optimal performance and reliability.
  • To configure the LT3470 for a specific output voltage, use the feedback resistors (R1 and R2) to set the output voltage. The output voltage is determined by the ratio of R1 to R2, according to the formula: Vout = 0.8V x (1 + R2/R1).
  • The EN (enable) pin on the LT3470 is used to enable or disable the regulator. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
