LT3990IMSE#TRPBF Frequently Asked Questions (FAQs)

• What is the maximum input voltage that the LT3990 can handle?
  The LT3990 can handle input voltages up to 60V, but it's recommended to keep the input voltage below 50V for optimal performance and reliability.
• How do I ensure the stability of the output voltage?
  To ensure stability, make sure to use a minimum output capacitance of 10uF, and a maximum ESR of 1 ohm. Also, keep the output voltage within the recommended range of 1.2V to 15V.
• What is the maximum output current that the LT3990 can deliver?
  The LT3990 can deliver up to 2A of output current, but it's recommended to keep the output current below 1.5A for optimal performance and reliability.
• How do I configure the soft-start feature of the LT3990?
  The soft-start feature can be configured by connecting a capacitor from the SS pin to ground. The value of the capacitor determines the soft-start time, with larger values resulting in longer soft-start times.
• What is the purpose of the EN pin, and how do I use it?
  The EN pin is an enable input that allows the user to turn the regulator on or off. To enable the regulator, tie the EN pin to a logic high (VIN or higher), and to disable it, tie it to a logic low (GND).
