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.

Power Integrations Expands InnoSwitch4-CZ Integrated Switcher Family to 220 W

New high-voltage GaN switches boost efficiency to 95 percent, yielding ultra-compact USB PD 3.1 adapters

Power Integrations (NASDAQ: POWI), the leader in high-voltage integrated circuits (ICs) for energy-efficient power conversion, today announced an expanded offering of the InnoSwitch™4-CZ family of high-frequency, zero-voltage switching (ZVS) flyback controller ICs. When paired with Power Integrations' ClampZero™ active-clamp IC and, optionally, the recently announced HiperPFS™-5 GaN-based power-factor corrector, the new ICs easily address the latest USB PD 3.1 specification for adapters and chargers up to 220 W.

“Road warriors demand light, compact, powerful adapters capable of rapidly charging all their mission-critical devices. The expanded power range of the new InnoSwitch4-CZ and ClampZero ICs allows charger/adapter designers to easily exceed 23 W per cubic inch for single- and multiple-output USB PD 3.1 certified designs,” explained Edward Ong, senior product marketing manager at Power Integrations. “Even at 220 W of output power, the family’s high efficiency minimizes waste heat; bulky heatsinks are not required on any of the active devices. The maximum switching frequency of up to 140 kHz minimizes transformer size, and the high level of integration approximately halves the number of passive components, MOSFETs and diodes that make safety-compliant PCB layout a challenge.”

InnoSwitch4-CZ ICs include a robust 750 V PowiGaN™ primary switch, active clamp drive and synchronous rectification in a compact InSOP™-24D package. Secondary-side sensing – achieved using Power Integrations’ FluxLink™ high-speed communications technology – provides exceptional CV/CC accuracy.

Adds Ong: “The use of a non-complementary-mode active clamp enables designs that work in both continuous (CCM) and discontinuous (DCM) modes. By operating across modes, it is much easier to support the wide load/range conditions often encountered in USB PD applications.”

InnoSwitch4-CZ ICs consume less than 30 mW at no-load, including input line voltage monitoring. The ICs feature a comprehensive suite of protection features, including auto-restart or latching fault response for output over- and under-voltage; multiple output under-voltage fault thresholds; and latching or hysteretic primary over-temperature protection.

Availability & Resources

A super compact 130 W, USB PD adaptor reference design (DER-957) is available for designers wishing to evaluate the InnoSwitch4-CZ flyback controller IC and ClampZero active clamp IC chipset. Devices are priced starting at $3.07 for INN4072C-TL and $0.66 for CPZ1061M-TLXXX in 1,000-unit quantities of the chipset. For further information, contact a Power Integrations sales representative or one of the company’s authorized worldwide distributors: Digi-Key, Farnell, Mouser and RS Components, or visit power.com.
