Key Differentiators

  • Industrial temperature grade (vs LTM4700EY#PBF)
  • Lead-free (RoHS compliant) packaging (vs LTM4700IY)
  • Higher current capability than LTC3882 (vs LTC3882-1#PBF)

Design Notes

The LTM4700IY#PBF can dissipate significant power at high currents. For example, at 100A output and 1V output from 12V input, power loss is approximately 100W. Ensure adequate airflow or heatsinking. The µModule package has an exposed pad for thermal management; connect it to a large copper area on the PCB. Refer to the datasheet for thermal derating curves.

Place input and output capacitors close to the module pins to minimize parasitic inductance. Use multiple vias for high-current paths. Follow the layout guidelines in the datasheet, including proper grounding and decoupling. For PMBus signals, keep traces short and avoid noise sources.

Ensure the PMBus address is correctly configured via pin-strapping resistors. Do not exceed the maximum input voltage of 16V. Use the LTpowerPlay GUI to configure and monitor the module. Verify the output voltage sense connections to avoid errors due to trace resistance.
