LTM4633IY Frequently Asked Questions (FAQs)

  • The maximum output current of the LTM4633IY is 3A per phase, making it suitable for high-current applications.
  • To minimize EMI, it is recommended to follow a star-ground configuration, keep the high-current paths short and wide, and use a solid ground plane. Additionally, placing the input capacitors close to the VIN pins and the output capacitors close to the VOUT pins can help reduce EMI.
  • The recommended input capacitor type for the LTM4633IY is a low-ESR ceramic capacitor, such as an X5R or X7R dielectric capacitor, with a voltage rating of at least 2x the input voltage.
  • The LTM4633IY output voltage can be configured by adjusting the resistive divider ratio of the feedback resistors (RFBT and RFB) and the output voltage sense resistor (RSENSE). The output voltage can be calculated using the formula: VOUT = 0.6V x (1 + RFB/RFBT).
  • The thermal derating curve for the LTM4633IY can be found in the datasheet, which shows the maximum output current vs. ambient temperature. The curve indicates that the maximum output current decreases as the ambient temperature increases.
