LTC3547EDDB#TRMPBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 15V, but it's recommended to keep it below 12V for optimal performance and to prevent damage to the internal regulator.
  • 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, ensure that the input voltage is within the recommended range and the output current is within the specified limits.
  • The maximum output current that can be drawn from the LTC3547 is 1.5A, but it's recommended to keep it below 1.2A for optimal performance and to prevent overheating.
  • The output voltage can be adjusted by connecting a resistor divider network between the VOUT pin and the GND pin. The output voltage is determined by the ratio of the resistors in the divider network.
  • The EN (enable) pin is used to turn the regulator on or off. When the EN pin is high, the regulator is enabled, and when it's low, the regulator is disabled.
