LT8636EV#PBF Frequently Asked Questions (FAQs)

  • The maximum input voltage that the LT8636 can handle is 42V, but it's recommended to keep it below 36V for optimal performance and reliability.
  • To optimize the layout for the LT8636, keep the input and output capacitors close to the IC, use a solid ground plane, and minimize the length of the traces between the IC and the capacitors. Also, ensure that the input and output voltage rails are separated to minimize noise coupling.
  • The recommended input capacitor value is 10uF to 22uF, and it's recommended to use a low-ESR ceramic capacitor, such as an X5R or X7R type, to minimize voltage ripple and ensure stable operation.
  • The output voltage of the LT8636 can be set using a resistive divider network between the output and the FB pin. The recommended resistors are 1% tolerance, and the ratio of the resistors determines the output voltage.
  • The maximum output current that the LT8636 can deliver is 3A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
