About Cabling Installation & Maintenance

Our mission: Bringing practical business and technical intelligence to today's structured cabling professionals

For more than 30 years, Cabling Installation & Maintenance has provided useful, practical information to professionals responsible for the specification, design, installation and management of structured cabling systems serving enterprise, data center and other environments. These professionals are challenged to stay informed of constantly evolving standards, system-design and installation approaches, product and system capabilities, technologies, as well as applications that rely on high-performance structured cabling systems. Our editors synthesize these complex issues into multiple information products. This portfolio of information products provides concrete detail that improves the efficiency of day-to-day operations, and equips cabling professionals with the perspective that enables strategic planning for networks’ optimum long-term performance.

Throughout our annual magazine, weekly email newsletters and 24/7/365 website, Cabling Installation & Maintenance digs into the essential topics our audience focuses on.

  • Design, Installation and Testing: We explain the bottom-up design of cabling systems, from case histories of actual projects to solutions for specific problems or aspects of the design process. We also look at specific installations using a case-history approach to highlight challenging problems, solutions and unique features. Additionally, we examine evolving test-and-measurement technologies and techniques designed to address the standards-governed and practical-use performance requirements of cabling systems.
  • Technology: We evaluate product innovations and technology trends as they impact a particular product class through interviews with manufacturers, installers and users, as well as contributed articles from subject-matter experts.
  • Data Center: Cabling Installation & Maintenance takes an in-depth look at design and installation workmanship issues as well as the unique technology being deployed specifically for data centers.
  • Physical Security: Focusing on the areas in which security and IT—and the infrastructure for both—interlock and overlap, we pay specific attention to Internet Protocol’s influence over the development of security applications.
  • Standards: Tracking the activities of North American and international standards-making organizations, we provide updates on specifications that are in-progress, looking forward to how they will affect cabling-system design and installation. We also produce articles explaining the practical aspects of designing and installing cabling systems in accordance with the specifications of established standards.

65V, 2A Automotive-Compliant Synchronous Buck LED Driver From Diodes Incorporated for Lighting Applications With Comprehensive Protection and Fault Reporting

Diodes Incorporated (Diodes) (Nasdaq: DIOD) today announces the expansion of its automotive-compliant* LED driver portfolio by introducing the AL8891Q. This easy-to-use synchronous Buck LED driver with high-side current sense drives up to 2A from a wide 4.5V to 65V input voltage range. It supports up to 95% duty cycle, allowing the drive of longer LED chains. The device provides a flexible, high-efficiency solution for automotive lighting applications, including daytime running lights (DRL), fog lights, turn lights, brake/stop lights, and interior lights.

Using constant-on-time (COT) control, the AL8891Q achieves simple control-loop compensation and cycle-by-cycle current limiting with a fast transient response without requiring an external compensation capacitor. The device’s switching frequency is adjustable from 200kHz to 2.5MHz, allowing it to optimize efficiency or achieve a smaller inductor size and compact form factor. It incorporates a spread spectrum frequency modulation technique to enhance EMI performance, which eases compliance with the most stringent CISPR 25 Class 5 standard.

The AL8891Q has two independent pins—PWM and analog dimming—for enhanced functionality. PWM dimming, from 0.1kHz to 2kHz, is suitable for high-resolution dimming, and analog dimming is from 0.15V to 2V. It features an internal soft-start function, gradually increasing the inductor and switch current to minimize potential overvoltage and overcurrent at the output.

The device features comprehensive protections with fault reporting, including thermal shutdown with auto-restart, input and constant current undervoltage lockout (UVLO), cycle-by-cycle current limit, and LED-open & short circuit protection to help increase system robustness.

The AL8891Q is available in the thermally enhanced TSSOP-16EP package with an operating temperature range of -40°C to +125°C. It is available at $0.78 for 1,000-piece quantities. A standard compliance version, AL8891, is available and is suitable for industrial and commercial applications.
