MPN: LTM4700MPY#PBF ✓ نشطLTM4700MPY#PBF نظرة عامة
A μModule regulator is a complete power management solution that combines a DC/DC controller, power transistors, input and output capacitors, and inductors into a single encapsulated package. It belongs to the hierarchy of power modules, which are part of the broader category of power management integrated circuits (PMICs). By integrating all critical components, μModule regulators minimize external component count, reduce design complexity, and accelerate time-to-market for high-current applications.
Key features of the LTM4700 include a wide input voltage range of 4.5V to 16V, dual 50A or single 100A output capability, and an output voltage range of 0.5V to 1.8V. The device supports PMBus for digital power system management, enabling real-time telemetry monitoring of voltage, current, and temperature, as well as configuration of output voltage, current limits, and sequencing. The module achieves high efficiency, typically above 90%, and includes overvoltage, overcurrent, and overtemperature protection.
Technically, the LTM4700 employs a peak current mode control architecture with internal compensation, ensuring stable operation across a wide range of output capacitors. The digital interface allows precise voltage accuracy of ±0.5% and supports fault logging and margining. The module is designed for high-density computing, networking, and industrial applications where space and thermal management are critical.
Typical applications include high-performance FPGA, ASIC, and processor power supplies in data centers, telecom equipment, and industrial automation. The LTM4700's high current density and digital management capabilities make it ideal for powering advanced processors and memory systems.
When designing with the LTM4700, ensure adequate thermal management through proper PCB layout and airflow, as the module dissipates significant power at full load. The PMBus interface requires careful attention to I2C addressing and bus capacitance to ensure reliable communication.

ملاحظات التصميم
The LTM4700MPY#PBF can dissipate significant power at full load. For example, at 100A output and 1.8V, power dissipation is approximately 18W (assuming 90% efficiency). Ensure adequate airflow and consider a heatsink or thermal pad. The BGA package has an exposed thermal pad that must be soldered to a large copper area for heat spreading. Follow the layout guidelines in the datasheet for optimal thermal performance.
Place input and output capacitors close to the module pins to minimize parasitic inductance. Use multiple vias to connect the thermal pad to the ground plane. For high-current paths, use wide traces or copper pours to reduce resistance and heat. The PMBus lines (SDA, SCL) should be routed with proper pull-up resistors and kept away from noisy switching nodes.
Do not exceed the absolute maximum input voltage of 16V. Ensure the PMBus address is correctly set to avoid conflicts on the I2C bus. The output voltage is set via PMBus or external resistors; verify the configuration before power-up. Also, consider the input current rating and use appropriate input bulk capacitance to handle transient loads.
