**LTM4670IY#PBF: A High-Efficiency, Dual 13A Power Module with Digital Management**

In the realm of high-performance computing, telecommunications, and advanced instrumentation, the demand for compact, efficient, and intelligently managed power delivery is paramount. The **LTM4670IY#PBF** from Analog Devices stands as a pinnacle of integration, addressing these exact challenges by combining two high-current step-down DC/DC regulators and sophisticated digital management into a single, overmolded BGA package.

This µModule® regulator is engineered to deliver **two independent 13A outputs or a single polyphase 26A output** from a wide input voltage range of 4.5V to 26.5V. Its core strength lies in its exceptional **power density and efficiency**, achieving peak efficiencies exceeding 90%, which drastically reduces thermal dissipation and simplifies board design. The integrated solution includes switching controllers, power FETs, inductors, and supporting components, significantly saving valuable PCB space and accelerating time-to-market for complex systems.

A defining feature of the LTM4670IY#PBF is its **advanced digital management interface** via PMBus—an I²C-based serial protocol. This allows for real-time telemetry monitoring of key parameters such as output voltage, output current, temperature, and input power. Designers can digitally program and dynamically adjust output voltages with margining, set current limits, and configure fault management strategies, including overvoltage and overcurrent protection. This programmability offers unparalleled flexibility, enabling optimal power system optimization across various operating conditions.

The module's robust design ensures reliable operation in harsh environments, supported by a wide operating temperature range. Its **remote configurability and monitoring** capabilities make it an ideal choice for systems requiring high availability, such as enterprise servers, network routers, and storage arrays.

**ICGOOODFIND**: The LTM4670IY#PBF is a superior power solution that masterfully integrates high efficiency, dual high-current output, and comprehensive digital power management. It eliminates traditional design complexities, providing a compact, reliable, and highly configurable building block for advanced power architectures, ultimately enhancing system performance and reliability.
