The device supports digital power system management via PMBus, enabling real-time monitoring of voltage, current, and temperature, as well as programmable margining and sequencing. The MP grade ensures operation over the -55°C to 125°C internal temperature range, making it suitable for harsh environments.
Technically, the LTM4680 employs a peak current mode architecture with integrated high-performance power stages, achieving efficiencies up to 90%. The PMBus interface allows precise control and telemetry, reducing external component count and improving system reliability. The module is designed for high-current applications such as FPGA, ASIC, and processor power supplies, where tight voltage regulation and fast transient response are critical.
Typical applications include telecom and networking equipment, data center servers, and industrial systems requiring high-density power conversion. The LTM4680MPY#PBF is ideal for powering FPGAs, GPUs, and CPUs in these environments, providing clean, stable power rails with minimal external components.
When designing with this module, ensure adequate thermal management by providing sufficient copper area and airflow, as the module dissipates significant heat at full load. The PMBus interface should be configured for proper sequencing and monitoring to optimize system performance.

主要差異化特點
- Military temperature grade (-55°C to 125°C) (對比LTM4680IY#PBF)
- Higher output current than LTM4630AEY#PBF (對比LTM4630AEY#PBF)
- PMBus telemetry for digital power management (對比MxL7218-ABA-T)
設計說明
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.
