LTC1874EGN#PBF datasheet by Linear Technology

LTC1874EGN#PBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC1874EGN?
  The maximum input voltage that can be applied to the LTC1874EGN is 60V, but it's recommended to keep it below 50V for reliable operation.
• How do I ensure the stability of the LTC1874EGN in my design?
  To ensure stability, make sure to follow the recommended layout guidelines, use a low ESR output capacitor, and add a small ceramic capacitor (e.g., 10nF) between the VIN and GND pins to filter out high-frequency noise.
• What is the minimum input voltage required for the LTC1874EGN to operate?
  The minimum input voltage required for the LTC1874EGN to operate is 2.5V, but it's recommended to keep it above 3V for reliable startup and operation.
• Can I use the LTC1874EGN in a high-temperature environment?
  The LTC1874EGN is rated for operation up to 125°C, but it's recommended to derate the output current and input voltage as temperature increases to ensure reliable operation.
• How do I calculate the output voltage of the LTC1874EGN?
  The output voltage of the LTC1874EGN 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.
