Notas de diseño
The LTM4680MPY#PBF can dissipate significant power at full load. For example, at 60A output and 1V, power loss is approximately 6W (assuming 90% efficiency). Ensure adequate PCB copper area and airflow to keep the internal temperature within the -55°C to 125°C range. Use thermal vias under the module to enhance heat transfer.
Place input and output capacitors close to the module pins to minimize parasitic inductance. Use low-ESR ceramic capacitors for high-frequency decoupling. The PMBus lines should be routed with proper pull-up resistors and kept away from noisy switching nodes to ensure reliable communication.
Do not exceed the absolute maximum input voltage of 16V. Ensure the PMBus address is correctly configured to avoid conflicts on the bus. When paralleling modules for higher current, follow the manufacturer's guidelines for current sharing and phase interleaving to prevent thermal imbalance.
