Tiny power module delivers 100A
Release date:2019-07-15 Browse times:48


The step-down switching mode regulator combines high power with energy-efficient performance.

LTM4700 µModule regulator is a dual 50A or single 100A step-down DC/DC regulator that incorporates analog control loops, mixed-signal circuitry, power MOSFETs, inductors and supporting components. The module’s heatsink packaging technology enables increased server density and boosts data center throughout and computational power with minimal impact on system size and cooling costs, Mouser says.LTM7400-638 - Tiny power module delivers 100A

The 15×22mm device features an integrated 16-Bit ∆Σ ADC, along with DACs and internal EEPROM. It features remote configurability and telemetry-monitoring of power management parameters over a PMBus protocol. The device 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 400A output current.
