TDK Corporation has introduced 20 A versions of the TDK-Lambda i6A product family of non-isolated DC-DC converters. Capable of operating from an even wider input voltage of 9 V to 53 V, the i6A4W step-down converters deliver an output voltage that can be adjustable from 3.3 V to 15 V. These parts allow operation from 48 V inputs, and can be used as drop-in replacements for expensive isolated 1/16th converters driving 12 V POL devices in medical, communications, industrial, and test and measurement equipment.
In the 1/16th brick form factor, measuring 33 x 22.9 x 12.7mm, the converters can also be used in conjunction with single-output 12 V, 24 V, 36 V and 48 V output AC-DC power supplies to generate additional regulated high-current outputs, with or without battery backup.
With efficiencies of up to 97%, power losses are minimized, allowing the products to operate in harsh ambient temperatures of –40° C to +125° C even with low airflow requirements. The need for external output capacitance is reduced due to an optimized dynamic voltage response, thus reducing board space requirements.
The basic feature models include an output voltage adjustment pin, positive or negative logic remote on-off, remote sense, input under-voltage, and over-current and thermal protection. Full-feature models are equipped with a power-good signal, output voltage sequencing and the ability to synchronize the operating frequency to minimize system noise. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1, and carry the CE mark for the Low Voltage and RoHS2 Directives.

This annual conference for applied power electronics addresses issues of interest to the practicing power electronics engineer. Intended audience includes:
- Equipment OEMs that use power supplies and dc-dc converters in their equipment
- Designers of power supplies, dc-dc converters, motor drives, uninterruptable power supplies, inverters and any other power electronic circuits, equipment and systems
- Manufacturers and suppliers of components and assemblies used in power electronics
- Manufacturing, quality and test engineers involved with power electronics equipment
- Marketing, sales and anyone involved in the business of power electronics
- Compliance engineers testing and qualifying power electronics equipment or equipment that uses power electronics
The conference will address up-to-date multidisciplinary research needs and interdisciplinary aspects of wireless and RF technology. The central theme of WAMICON2018 will be "mm-Waves and Internet of Things (IoT) for Commercial and Defense." We welcome submissions on all aspects of mm-wave and IoT related technologies including antennas, passive and active circuits, communication theory, and system concepts.
In 2018, the IEEE Radar Conference arrives in vibrant Oklahoma City for the first time. Being centrally located in the US, OKC is known for great Southern cuisine, Midwestern hospitality, and a good helping of Wild West cowboy culture. Nearby Norman, OK is also the home of NOAA’s National Severe Storms Laboratory and the Advanced Radar Research Center at the University of Oklahoma, who collectively have driven much of the modern-day weather radar technology in the US. Do not miss this exciting week filled with novel radar advances and down-home fun.
A one-day expo held each year in New York, Los Angeles and London designed to connect startups with the resources they need to grow.
