LT3470AIDDB#TRMPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the LT3470A is 15V, but it's recommended to keep it below 12V for optimal performance and reliability.
  • To ensure the stability of the output voltage, it's essential to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Additionally, the output voltage should be decoupled with a 10nF ceramic capacitor.
  • The maximum output current that the LT3470A can deliver is 700mA per channel, but it's recommended to keep it below 500mA for optimal performance and reliability.
  • The output voltage of the LT3470A can be configured by using a resistive divider network between the output and the feedback pin. The ratio of the resistors determines the output voltage, and the datasheet provides a formula to calculate the required resistor values.
  • The thermal shutdown temperature of the LT3470A is 150°C. When the junction temperature exceeds this value, the device will shut down to prevent damage.
