LTC3642EDD#TRPBF datasheet by Linear Technology

LTC3642EDD#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC3642EDD?
  The maximum input voltage that can be applied to the LTC3642EDD is 36V, but it's recommended to keep it below 30V for reliable operation.
• How do I ensure the LTC3642EDD operates within its thermal limits?
  To ensure the LTC3642EDD operates within its thermal limits, make sure to provide adequate heat sinking, keep the ambient temperature below 85°C, and avoid high power dissipation during operation.
• Can I use the LTC3642EDD in a high-temperature environment?
  While the LTC3642EDD can operate up to 125°C, it's not recommended for use in high-temperature environments above 105°C without proper derating and thermal management.
• How do I configure the LTC3642EDD for a specific output voltage?
  To configure the LTC3642EDD for a specific output voltage, use the FB pin and an external resistor divider network to set the desired output voltage. Refer to the datasheet for the calculation formula and example circuits.
• What is the minimum input capacitance required for the LTC3642EDD?
  The minimum input capacitance required for the LTC3642EDD is 10uF, but it's recommended to use a higher value (e.g., 22uF) for better input filtering and stability.
