Dual 50A or single 100A configuration available
Suitable for cloud, optical networks, PCIe, etc.
Combines up to 8 devices, providing 800A load current
Analog Devices announced today the launch of the LTM4700 step-down DC/DC power regulator, expanding its micromodule regulator product line.

The new LTM4700 delivers the energy-efficient performance needed to alleviate data center infrastructure cooling requirements. Available in dual 50A or single 100A configurations, this new micromodule regulator leverages Analog Devices' proprietary packaging technology to minimize system size and cooling costs while increasing server density and enhancing data center processing and compute performance.

The LTM4700 micromodule integrates onboard memory, data conversion circuitry, and digital interfaces into a highly integrated component-on-package design that is half the size of comparable devices. The new products are suitable for applications such as cloud computing, high-speed computing and optical network systems, communication infrastructure, PCIe boards, as well as medical, industrial, and instrumentation equipment.

Unlike other modular solutions that typically operate at 90°C, the LTM4700 operates at 73°C due to its heatsink packaging technology. The LTM4700 delivers 100A of output current at 12VIN, 0.8VOUT with 200 LFM airflow and a 70°C ambient temperature.

The maximum conversion efficiency is 90% at 12VIN and 0.8VOUT. The new micromodule products also adopt an architecture that allows parallel connection. For example, when data center processors such as FPGAs, ASICs, GPUs, and MCUs require higher power, designers can meet these power requirements by combining up to eight devices to provide a load current of 800A.

The LTM4700 operates over an input range of 4.5V to 16V, and its output voltage can be digitally controlled from 0.5V to 1.8V. Integrated ADCs, DACs, and EEPROM allow users to digitally monitor, store, and control power parameters using an I²C PMBus interface.

For noise-sensitive applications, the switching frequency can be synchronized to an external clock within the range of 200 kHz to 1 MHz. The LTM4700 also provides self-protection and load protection against fault conditions such as overvoltage, undervoltage, overcurrent, and overtemperature.

“Efficient cooling is a core requirement across all data centers, and the growing demand for higher processing power and cloud-based computing services is placing additional strain on existing data center infrastructure,” said Chris Mann, vice president of power products at Analog Devices. “This requires a new approach to heat dissipation, and the new LTM4700 addresses this challenge effectively, enabling data center operators to increase server density and performance.”
