DC-DC Power Regulator Eases Data Center Cooling Costs

Analog Devices (ADI) has expanded its suite of Power by Linear µModule regulators with the LTM4700 step-down DC/DC power regulator. The device features energy efficient performance that reduces data center infrastructure cooling requirements. Configured as dual 50 A or single 100A configuration, the power µModule’s packaging technology enables an increasing server density and boosts data center throughout and computational power with minimal impact on system size and cooling costs.

The LTM4700 µModule’s highly integrated, component-on-package design includes on-board memory, data conversion circuitry and digital interface, reducing it to nearly half the size of competing devices, according to ADI. 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.

The LTM4700 operates at 73°C using heatsink packaging technology. That’s much cooler compared to modular solutions from competitors which typically run at 90°C, says ADI. The device can deliver full 100 A at 12 VIN to 0.8 VOUT with 200 LFM air flow up to 70°C ambient temperature. Peak conversion efficiency at 12 VIN to 0.8 VOUT reaches 90%.  The µModule’s architecture also 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.

The LTM4700 operates from a 4.5 V to 16 V input range, with output voltages digitally controlled from 0.5 V to 1.8 V. Integrated A/D converters, D/A converters and EEPROM enable users to digitally monitor, record and control power parameters using an I²C PMBus interface. Switching frequency is synchronized to an external clock from 200 kHz to 1 MHz for noise-sensitive applications. The LTM4700 also has self- and load-protection features against fault conditions such as over- and undervoltage, overcurrent and overtemperature.

Summary of Features:

  • Dual 50 A or Single 100 A Digitally Adjustable Outputs with Digital Interface for Control, Compensation and Monitoring
  • Wide Input Voltage: 4.5 V to 16 V
  • Output Voltage Range: 0.5 V to 1. 8V
  • ~90% Full Load Efficiency from 12 VIN to 1 VOUT at 100 A
  • ±0.5% Maximum DC Output Error Over Temperature

Pricing for LTM4700 starts at $97.26 (1,000s) in a 15 mm x 22 mm x 7.87 mm BGA package.

TRENDS & CHOICES IN EMBEDDED COMPUTING

Comms and Control for Drones
Consumer and commercial drones represent one of the most dynamic areas of embedded design today. Chip, board and system suppliers are offering improved ways for drones to do more processing on board the drone, while also providing solutions for implementing the control and communication subsystems in drones. This article by Circuit Cellar’s Editor-in-Chief Jeff Child looks at the technology and products available today that are advancing the capabilities of today’s drones.

Choosing an MPU/MCU for Industrial Design
By Microchip Technology’s Jacko Wilbrink
As MCU performance and functionality improve, the traditional boundaries between MCUs and microprocessor units (MPUs) have become less clear. In this article, Jacko examines the changing landscape in MPU vs. MCU capabilities, OS implications and the specifics of new SiP and SOM approaches for simplifying higher-performance computing requirements in industrial applications.

Product Focus: COM Express Boards
The COM Express architecture has found a solid and growing foothold in embedded systems. COM Express boards provide a complete computing core that can be upgraded when needed, leaving the application-specific I/O on the baseboard. This Product Focus section updates readers on this technology and provides a product album of representative COM Express products.

MICROCONTROLLERS ARE DOING EVERYTHING

Connecting USB to Simple MCUs
By Stuart Ball
Sometimes you want to connect a USB device such as a flash drive to a simple microcontroller. Problem is most MCUs cannot function as a USB host. In this article, Stuart steps through the technology and device choices that solve this challenge. He also puts the idea into action via a project that provides this functionality.

Vision System Enables Overlaid Images
By Daniel Edens and Elise Weir
In this project article, learn how these two Cornell students designed a system to overlay images from a visible light camera and an infrared camera. They use software running on a PIC32 MCU to interface the two types of cameras. The MCU does the computation to create the overlaid images, and displays them on an LCD screen.

DATA ACQUISITION AND MEASUREMENT

Data Acquisition Alternatives
By Jeff Child
While the fundamentals of data acquisition remain the same, its interfacing technology keeps evolving and changing. USB and PCI Express brought data acquisition off the rack, and onto the lab bench top. Today solutions are emerging that leverage Mini PCIe, Thunderbolt and remote web interfacing. Circuit Cellar’s Editor-in-Chief, Jeff Child, dives into the latest technology trends and product developments in data acquisition.

High-Side Current Sensing
By Jeff Bachiochi
Jeff says he likes being able to measure things—for example, being able to measure load current so he can predict how long a battery will last. With that in mind, he recently found a high-side current sensing device, Microchip’s EMC1701. In his article, Jeff takes you through the details of the device and how to make use of it in a battery-based system.

Power Analysis Capture with an MCU
By Colin O’Flynn
Low-cost microcontrollers integrate many powerful peripherals in them. You can even perform data capture directly to internal memory. In his article, Colin uses the ChipWhisperer-Nano as a case study in how you might use such features which would otherwise require external programmable logic.

TOOLS AND TECHNIQUES FOR EMBEDDED SYSTEM DESIGN

Easing into the IoT Cloud (Part 2)
By Brian Millier
In Part 1 of this article series Brian examined some of the technologies and services available today enabling you to ease into the IoT cloud. Now, in Part 2, he discusses the hardware features of the Particle IoT modules, as well as the circuitry and program code for the project. He also explores the integration of a Raspberry Pi solution with the Particle cloud infrastructure.

Hierarchical Menus for Touchscreens
By Aubrey Kagan
In his December article, Aubrey discussed his efforts to build a display subsystem and GUI for embedded use based on a Noritake touchscreen display. This time he shares how he created a menu system within the constraints of the Noritake graphical display system. He explains how he made good use of Microsoft Excel worksheets as a tool for developing the menu system.

Real Schematics (Part 2)
By George Novacek
The first part of this article series on the world of real schematics ended last month with wiring. At high frequencies PCBs suffer from the same parasitic effects as any other type of wiring. You can describe a transmission line as consisting of an infinite number of infinitesimal resistors, inductors and capacitors spread along its entire length. In this article George looks at real schematics from a transmission line perspective.
