LTC3414MPFE#PBF datasheet by Linear Technology

LTC3414MPFE#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the VIN pin?
  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 reliability.
• How do I ensure the stability of the output voltage when using the LTC3414?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, ensure that the output voltage is within the recommended range of 0.8V to 5.5V.
• What is the purpose of the RUN pin, and how do I use it?
  The RUN pin is an active-high enable input that allows the user to turn the regulator on and off. To use it, simply tie it to VIN or a logic signal to enable the regulator, or tie it to GND to disable it.
• How do I calculate the output voltage of the LTC3414?
  The output voltage can be calculated using the formula: VOUT = 0.8V x (1 + R1/R2), where R1 and R2 are the resistors connected to the FB pin. The ratio of R1 to R2 determines the output voltage.
• What is the maximum current that the LTC3414 can deliver?
  The maximum current that the LTC3414 can deliver is 1.5A, but it's recommended to keep the output current below 1.2A for optimal performance and reliability.
