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.

The 2016 event was mentioned in our writeup on a startup from USC that built interest in their affordable AR device while sharing cabin space with venture capitalists onboard a chartered flight to the event.
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.
For more than 30 years, the combined annual Symposia on VLSI Technology and Circuits has been the world’s premier mid-year conference for microelectronics technology, providing an opportunity for the world’s top device technologists, circuit and system designers to exchange leading-edge ideas. Held together since 1987, the Symposia on VLSI Technology and Circuits have alternated each year between sites in the US and Japan, enabling attendees to learn about new directions in the development of VLSI technology & circuit design through the industry’s leading research and development presentations.
The comprehensive technical programs at the two Symposia – fully overlapping again this year – are supplemented with short courses, invited speakers and several evening panel sessions. Since 2012, the Symposia have presented joint focus sessions that include invited and contributed papers on topics of mutual interest to both technology and circuit attendees. A single registration enables participants to attend both Symposia.
