Transphorm’s High Voltage GaN FETs Amp Up Marotta Controls’ Military Grade High Frequency Power Supply

Jaa

Transphorm Inc.—the leader in the design and manufacturing of the highest reliability and first JEDEC- and AEC-Q101 qualified gallium nitride (GaN) semiconductors—today announced with Marotta Controls that the Aerospace and Defense supplier’s upcoming power supply unit (PSU) replaces incumbent Silicon (Si) MOSFETs with high voltage GaN PQFN devices to offer advanced benefits.

Marotta’s latest design operates at high frequency in a conduction-cooled mechanically constrained envelope. The supply’s topology features hard switching and an automatic transformer RESET capability where transistor voltage stresses are clamped to the input voltage. The GaN devices increase the PSU’s efficiency dramatically and alleviate a complex thermal design in the small form factor package.

“The demand on our power supplies and expectation of performance is high,” explained Mike Scruggs, Principal Engineer, Marotta Controls. “This particular complex PSU needed to reliably convert and distribute power in a small envelope. The system design had to work considerably higher than 100 KHz to reduce the power component’s size, but our engineering team met challenges with heat dissipation and component temperatures under peak load conditions. In our search beyond standard transistor solutions we were led to find Transphorm’s high voltage GaN technology.”

After testing Si-based prototypes, Marotta vetted Transphorm’s TPH3208LD PQFN package. The TPH3208LD reached the desired switching speeds with significantly reduced losses. The GaN devices’ dissipation significantly decreased compared to that of the Si MOSFETs’, resulting in lower board component temperatures. This, in turn, yielded a simpler viable thermal design and packaging concept for the overall system.

“We initially selected Transphorm’s transistors for the reputable reliability and our experience has since exceeded our expectations,” stated Steve Fox, Vice President of Engineering and Program Management and CTO, Marotta Controls. “Transphorm’s GaN enabled us to not only gain high power efficiency and thermal performance, but also generated power savings in the drive and control circuitry—additional benefits that will provide opportunities in future designs. Transphorm’s ability to align with our vision of providing advanced, next-generation technologies combined with their exceptional level of technical support and dependability are the exact characteristics we look for in our growing supplier base.”

“Notably, Marotta’s design success is important for several reasons,” said Philip Zuk, Vice President of Worldwide Technical Marketing, Transphorm. “First, it indicates yet another hard-switched topology type that can effectively leverage high voltage GaN. Second, Marotta completed its design with minimal assistance from Transphorm’s application support team—indicating that the market’s initial concern that design challenges would slow GaN adoption can be addressed through the use of Transphorm’s GaN FETs.”

Release of Marotta’s high frequency PSU is slated for January 2019. The product will mark the Aerospace and Defense industry’s first publicly recognized high-voltage-GaN-based power supply.

RIBOMIC Announces Positive Top-Line Results from the Phase 1/2a Clinical Trial of RBM-007 (SUSHI Study) in Subjects with Wet Age-Related Macular Degeneration17.6.2019 16:15:00 EESTTiedote

RIBOMIC, Inc., a clinical stage pharmaceutical company specializing in aptamer therapeutics and traded on the Mothers Market of the Tokyo Stock Exchange (Code Number: 4591), today announced positive top-line results from its SUSHI study, Phase 1/2a single ascending dose clinical study of RBM-007, anti-FGF2 aptamer, in nine subjects with wet Age-Related Macular Degeneration (wet AMD). SUSHI study achieved the primary endpoint of safety and tolerability, and also demonstrated efficacy trends in favor of RBM-007. Subjects recruited for the SUSHI Study had wet AMD that was poorly responsive to previous intravitreal anti-VEGF therapy. Through the 56-Day exit visit, excluding one uncompleted case in the last cohort, single dose of RBM-007 demonstrated no dose-limiting toxicities, no systemic or ocular serious adverse events. One subject in Cohort 3 showed anterior inflammation, which was resolved after one day of topical prednisolone treatment. Rescue treatment with anti-VEGF therapy was ava

ECB Chooses SIA And Colt for the Access Network to the Eurosystem’s Payments, Securities and Collateral Infrastructures17.6.2019 16:00:00 EESTTiedote

SIA, in partnership with Colt Technology Services, has won a tender commissioned by the European Central Bank for the provisioning of connectivity services allowing European central and commercial banks, central depositories, automated clearing houses and other payment service providers to connect directly to Eurosystem market infrastructures through a single access interface (Eurosystem Single Market Infrastructure Gateway - ESMIG). Thanks to the concession granted to SIA and Colt as Network Service Providers for the ESMIG, starting from November 2021, all the key organisations in the European financial system will be able to access the platform for the settlement of large-value payments TARGET2, the instant payments settlement service TIPS, the securities settlement platform TARGET2-Securities (T2S), the Eurosystem Collateral Management System (ECMS) and possibly other new services and applications.

GSMA Debunks False Claims Threatening Future of 5G17.6.2019 14:04:00 EESTTiedote

The GSMA today hit out against false claims that 5G systems will harm other services, such as weather forecasting. The mobile industry has already demonstrated within leading international standards bodies that 5G can be used safely alongside other services, including weather sensing services, commercial satellite, radar and other applications using adjacent airwaves. The GSMA is confident that 5G services and weather sensing services can co-exist, and warns against giving credence to those claiming a negative impact from 5G networks on weather forecasting data. “5G and weather forecasts can and will co-exist – it’s ludicrous to suggest otherwise,” said Brett Tarnutzer, Head of Spectrum, GSMA. “To suggest that our 7-day forecast will go away with 5G is simply fake news. We cannot allow these scare tactics to prevent us from reaping the huge societal and economic benefits of 5G networks. We urge everyone to simply look at the facts and not get drawn in by misleading rhetoric.” The fact
