LT3990IMSE-5#PBF Frequently Asked Questions (FAQ)

  • The LT3990 can handle input voltages up to 60V, but it's recommended to operate within the specified input voltage range of 4.5V to 40V for optimal performance.

  • To ensure stability, it's essential to follow the recommended layout and component selection guidelines, including the use of a minimum 10uF output capacitor with a low ESR, and a 1uF input capacitor.

  • The LT3990 can deliver up to 2A of output current, but it's recommended to operate within the specified output current range of 0A to 1.5A for optimal performance and thermal considerations.

  • The output voltage of the LT3990 can be adjusted by using a resistive divider network between the output and the FB pin, with the ratio of the resistors determining the output voltage.

  • The EN (enable) pin is used to enable or disable the regulator. When the EN pin is pulled high, the regulator is enabled, and when it's pulled low, the regulator is disabled. This pin can be used to implement power sequencing or to shut down the regulator during standby modes.
