Switch mode regulator helps cool down data centres

It is a dual 50A or single 100A step-down DC/DC regulator solution that incorporates fast analogue control loops, precision mixed-signal circuitry, power MOSFETs, inductors and supporting components.

An innovative heatsink packaging technology enables increased server density and boosts data centre throughout and computational power with minimal impact on system size and cooling costs.

The 15 × 22mm device integrates analogue-to-digital converters (ADCs), digital-to-analogue converters (DACs), and EEPROM and features remote configurability and telemetry-monitoring of power management parameters over a PMBus protocol.

It operates over an input voltage range of 4.5V to 16V, with a digitally supported output voltage range of 0.5V to 1.8V.

The µModule’s architecture enables system designers to combine up to eight devices, delivering up to 800A of load current to meet the higher power needs of data center processors, including FPGAs, ASICs, GPUs and microcontrollers.

Applications include cloud computing, high-speed computing and optical networking systems, communication infrastructure, and PCIe boards, as well as medical, industrial, and test and measurement equipment.

Mouser also stocks LTM4700 demonstration boards, which include up to four LTM4700 regulators on a board for up to 400 A output current.

The boards power up to default settings and produce power based on configuration resistors without the need for any serial bus communication, enabling easy evaluation of the LTM4700 µModule device.
