LTC4055EUF#TRPBF datasheet by Linear Technology

LTC4055EUF#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the LTC4055EUF?
  The maximum input voltage that can be applied to the LTC4055EUF is 18V, but it's recommended to keep it below 15V for reliable operation.
• How do I ensure the LTC4055EUF is properly thermally managed?
  Proper thermal management can be achieved by providing a heat sink or a thermal pad on the exposed pad of the QFN package, and ensuring good airflow around the device.
• What is the recommended input capacitor value and type for the LTC4055EUF?
  A 10uF to 22uF X5R or X7R ceramic capacitor is recommended for the input capacitor, placed as close to the VIN pin as possible.
• Can I use the LTC4055EUF in a high-temperature environment?
  The LTC4055EUF is rated for operation up to 125°C, but the maximum junction temperature should not exceed 150°C. Derate the output current and ensure proper thermal management for high-temperature operation.
• How do I configure the LTC4055EUF for a specific output voltage?
  The output voltage can be set using an external resistor divider network connected to the FB pin. The datasheet provides a formula to calculate the required resistor values for a specific output voltage.
