Analog Devices Inc. LTM4678IY#PBF Dual 25A or Single 50A µModule Regulator

The LTM4678IY#PBF is a highly versatile and efficient dual 25A or single 50A µModule (micromodule) regulator from Analog Devices Inc. Designed to cater to a wide range of applications, this advanced power management solution integrates top-notch power electronics, digital control, power management, and thermal management within a compact, surface-mount package.

Featuring a wide input voltage range of 4.5V to 17V and an output voltage range of 0.5V to 5.5V, the LTM4678 is capable of delivering up to 50A of continuous output current with exceptional precision. This makes it an ideal choice for powering FPGAs, ASICs, microprocessors, and dense PCB layouts that require high power delivery in a limited space.

The LTM4678IY#PBF utilizes a dual-phase step-down switching mode architecture that can be paralleled to deliver a single 50A output. Its high efficiency and fast transient response are ensured by the use of a proprietary control loop design and state-of-the-art MOSFETs. The device also supports frequency synchronization, spread spectrum operation, and has selectable burst mode operation for improved light load efficiency.

One of the key features of the LTM4678 is its PMBus/I2C-based system interface, which allows for real-time monitoring and control of the power system. Users can leverage this interface to access telemetry data such as input and output voltages, currents, temperatures, and fault status. Furthermore, the LTM4678's built-in EEPROM enables users to store and recall custom settings and configurations, streamlining the design process and reducing time to market.

The LTM4678IY#PBF is designed with reliability in mind, featuring overvoltage, overcurrent, and overtemperature protection. Its robust package ensures excellent thermal performance and is suitable for operation in environments with ambient temperatures ranging from -40°C to 125°C.

With its advanced features, compact size, and ease of use, the LTM4678IY#PBF from Analog Devices Inc. represents a state-of-the-art solution for modern high-density power applications that demand high efficiency, precision, and reliability.
