**LTM4680IY: A High-Efficiency, Dual 9A or Single 18A μModule Regulator with Digital Power System Management**

In the demanding landscape of modern electronics, power delivery solutions must achieve a delicate balance of high performance, compact footprint, and intelligent management. The **LTM4680IY** from Analog Devices stands out as a premier solution, addressing these challenges by integrating a complete, high-efficiency switching regulator with advanced digital control into a single, easy-to-use package.

This μModule (micromodule) regulator is exceptionally versatile. It can be configured as **two independent 9A output channels** or be paralleled to function as a **single 18A output channel**, providing design engineers with significant flexibility for powering high-current devices like FPGAs, ASICs, and processors. Its high level of integration includes switching controllers, power FETs, inductors, and supporting components, all housed within a compact 16mm x 16mm x 5.01mm BGA package. This drastically reduces the design cycle, minimizes the PCB footprint, and alleviates the typical challenges associated with high-current layout and EMI.

A key differentiator of the LTM4680IY is its **integrated digital power system management (PSM)** capabilities. Through an I²C or PMBus interface, designers can monitor, control, and adjust power parameters in real-time. This includes **programming output voltage**, margining, monitoring **input and output currents**, voltage, temperature, and setting fault management limits. The ability to digitally trim output voltages optimizes system performance, while comprehensive telemetry allows for predictive health monitoring and enhanced system reliability.

Furthermore, the regulator boasts **exceptional power conversion efficiency**, minimizing power loss and thermal dissipation even at high load currents. Advanced control schemes, such as peak current mode control and optional discontinuous mode operation at light loads, contribute to this high efficiency across a wide operating range.

**ICGOOODFIND**: The LTM4680IY is a superior power management solution that combines the design simplicity of a module with the intelligence of a digital interface. Its dual/single output flexibility, high output current capability, and comprehensive telemetry make it an indispensable component for advanced computing, telecommunications, and data storage systems where power density, efficiency, and reliability are paramount.
