The Power by Linear LTM4700 µModule regulator from Analog Devices is a step-down switching mode regulator combining very high power with energy-efficient performance to aid in reducing data centre infrastructure cooling demands.
The regulator is a dual 50A or single 100A step-down DC-DC regulator solution that includes precision mixed-signal circuitry, fast analog control loops, power MOSFETs, inductors and supporting components. The module’s innovative heatsink packaging technology allows increased server density and boosts data centre throughout and computational power with minimum impact on system size and cooling costs.
The 15mm x 22mm device integrates ADCs, DACs, and EEPROM and highlights remote configurability and telemetry-monitoring of power management parameters over a PMBus protocol. The device runs over an input voltage range of 4.5V to 16V, with a digitally supported output voltage range of 0.5V to 1.8V.
The device’s architecture allows system designers to combine up to eight devices, producing up to 800A of load current to satisfy the higher power demands of data centre processors, including FPGAs, ASICs, GPUs and microcontrollers. Applications include high-speed computing and optical networking systems, cloud computing, communication infrastructure, and PCIe boards, as well as industrial, medical, and test and measurement equipment.
