Key Differentiators
- Military temperature range (-55°C to 125°C) (vs LTM4676IY#PBF)
- Dual 13A or single 26A output capability (vs LTM4676AIY#PBF)
- PMBus digital interface with telemetry (vs LTM4676EY#PBF)
Design Notes
The LTM4676MPY#PBF can dissipate significant power at high output currents. Ensure adequate thermal management by connecting the thermal pad to a large copper area on the PCB. Use multiple vias to transfer heat to inner layers. For dual 13A operation, consider forced air cooling or a heatsink to keep the junction temperature within limits.
Place input and output capacitors close to the module pins to minimize parasitic inductance. Use low-ESR ceramic capacitors for high-frequency decoupling. The BGA package requires careful routing of the PMBus lines to avoid noise. Follow the layout guidelines in the datasheet for optimal performance.
Ensure the PMBus address is correctly configured to avoid conflicts on the bus. Also, verify the EEPROM settings for startup voltage and sequencing. Do not exceed the absolute maximum input voltage of 26.5V. Use proper pull-up resistors on the PMBus lines as specified in the datasheet.
