LTM4676MPY#PBF Visão geral
A μModule regulator is a complete DC/DC power supply in a single package, combining the controller, power switches, inductors, and compensation circuitry to simplify design and reduce board space. It belongs to the hierarchy: μModule regulator -> DC/DC converter -> power management IC -> semiconductor. This integration eliminates the need for external inductor selection and loop compensation, significantly reducing design risk and time-to-market.
Key features include dual 13A or single 26A output capability, PMBus digital interface for configuration and telemetry, and a wide input voltage range of 4.5V to 26.5V. The device supports output voltages from 0.5V to 5.4V, making it suitable for powering FPGAs, ASICs, and processors. The LTM4676MPY#PBF is the military-grade version, guaranteed to meet performance specifications over the -55°C to 125°C internal operating temperature range, ensuring reliability in harsh environments.
Technically, the LTM4676 integrates high-efficiency power stage with digital power system management, allowing real-time monitoring of output voltage, current, and temperature. The PMBus interface enables remote configuration of output voltage, current limits, and sequencing, which is essential for complex multi-rail systems. The device also features fast analog control loops for excellent transient response, and its EEPROM stores configuration data for autonomous startup.
Typical applications include high-performance computing, data center servers, telecommunications equipment, and industrial systems where precise voltage regulation and digital management are required. The wide input range and high output current make it ideal for powering FPGAs, GPUs, and network processors.
When designing with this device, ensure adequate thermal management due to high power dissipation. The BGA package requires a thermal pad connection to a large copper area for heat spreading. Also, configure the PMBus parameters carefully to match the load requirements and sequencing needs.

Notas de projeto
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.
