LTC3443EDE#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the VIN pin is 5.5V, as specified in the Absolute Maximum Ratings section of the datasheet. Exceeding this voltage can damage the device.
  • To ensure the stability of the output voltage, it is recommended to use a minimum output capacitance of 10uF with an ESR of 1Ω or less, as specified in the datasheet. Additionally, the output voltage should be decoupled from the input voltage using a capacitor with a value of 1uF or more.
  • The maximum output current that the LTC3443EDE can deliver is 1.5A, as specified in the datasheet. However, the actual output current may be limited by the input voltage, output voltage, and thermal considerations.
  • The output voltage can be configured by connecting the VOUT pin to the FB pin through a resistive divider network. The ratio of the resistors determines the output voltage, as described in the datasheet. For example, to set the output voltage to 3.3V, R1 can be 1kΩ and R2 can be 2.2kΩ.
  • The EN pin is an active-high enable input that allows the device to be turned on or off. When the EN pin is high, the device is enabled and operates normally. When the EN pin is low, the device is disabled and the output voltage is disconnected from the input voltage. This pin can be used to implement power sequencing or to turn off the device when not in use.
