LTM4634IY Frequently Asked Questions (FAQs)

  • The maximum output current of the LTM4634IY is 3A per phase, making it suitable for high-current applications.
  • To optimize the layout, keep the high-current paths short and wide, use a solid ground plane, and place the input and output capacitors close to the device. Also, ensure that the thermal pad is connected to a solid ground plane to improve thermal performance.
  • The recommended input capacitor value is 10uF to 22uF, with an X7R or X5R dielectric, and a voltage rating of at least 2x the input voltage.
  • The output voltage can be set using the FB pin and an external resistor divider network. The resistor values can be calculated using the formulae provided in the datasheet.
  • The thermal derating curve is provided in the datasheet, and it shows the maximum output current vs. ambient temperature. The device can operate up to 125°C, but the output current must be derated accordingly.
