LTC3890EGN-3#PBF Frequently Asked Questions (FAQs)

  • The maximum junction temperature of the LTC3890EGN-3#PBF is 125°C. This is specified in the absolute maximum ratings section of the datasheet.
  • Yes, the LTC3890EGN-3#PBF is available in a high-reliability version (LTC3890EGN-3#PBF-HR) and an automotive version (LTC3890EGN-3#PBF-A). These versions have additional testing and screening to ensure higher reliability and performance in demanding environments.
  • Analog Devices provides a layout guide and thermal management guidelines in the datasheet and application notes. Additionally, it is recommended to follow general high-frequency PCB layout best practices, such as separating analog and digital grounds, using a solid ground plane, and minimizing trace lengths and loops.
  • The recommended input capacitor value is 10uF to 22uF, and a low-ESR ceramic capacitor (such as X5R or X7R) is recommended. The input capacitor should be placed as close as possible to the VIN pin and should have a low impedance path to the PGND pin.
  • Yes, the LTC3890EGN-3#PBF can be used in a synchronous buck converter configuration. In this configuration, the internal high-side switch and the external low-side switch are synchronized to reduce power losses and improve efficiency.
