ROHM has expanded the library of SPICE model lineup for LTspice® of its circuit simulator. LTspice® is also equipped with circuit diagram capture and waveform viewer functions that make it possible for designers to check and verify in advance whether the circuit operation has been achieved as designed.
In addition to the existing lineup of bipolar transistors, diodes, and MOSFETs, ROHM has added SiC power devices and IGBTs that increases its number of LTspice® models to more than 3,500 for discretes (which can be downloaded from product pages). This brings the amount of coverage of LTspice® models on ROHM’s website to over 80% of all products – providing greater convenience to designers when using circuit simulators that incorporate discrete products, now including power devices.
In recent years, the increasing use of circuit simulation for circuit design has expanded the number of tools being utilized. Among these, LTspice® is an attractive option for a range of users, from students to even seasoned engineers at well-known companies. To support these and other users, ROHM has expanded its library of LTspice® models for discrete products.
Besides product pages, ROHM has added a Design Models page in October that allows simulation models to be downloaded directly. Documentation on how to add libraries and create symbols (schematic symbols) is also available to facilitate circuit design and simulation execution.
Going forward, ROHM will continue to contribute to solving circuit design issues by expanding the number of models compatible with various simulators while providing web tools such as ROHM Solution Simulator to meet growing customer needs.

Efficient Energy Technology GmbH (EET), the Austrian-based pioneer in designing and producing innovative balcony power plants, has selected Efficient Power Conversion Corporation’s (EPC) EPC2204 enhancement-mode gallium nitride (eGaN®) power transistor for its latest SolMate® green solar balcony product.
The EPC2204 strikes an optimal compromise between low RDS(on) and low COSS, critical for demanding hard switching application, while featuring a drain-source breakdown voltage of 100 V in a compact package. This compact design significantly reduces PCB size, keeps current loops small, and minimizes electromagnetic interference (EMI) emissions.
EET has realized multiple benefits following the integration of GaN in its SolMate MPPT charging converter. Efficiency loss has been halved, increasing overall efficiency from 96% to 98%. The converter’s volume has decreased by 70%, the BOM and manufacturing costs have been reduced by 20%, all while lowering cooling requirements. Additionally, the increased switching frequency by a factor of 10 eliminates the need for error-prone electrolytic capacitors, thus increasing the converter’s lifespan.
By reducing power loss, EET’s system can more efficiently convert solar energy, allowing the company to generate several megawatts of additional green solar power that would otherwise dissipate as heat on a large scale. The reduced cooling requirements are particularly significant in scenarios without access to fresh air, where a water-resistant case is employed.
EET’s SolMate has won many awards for its technical innovation, for the high technical standards and the innovative design, including the James Dyson Award, Living Standards Austria, the German Sustainability Award (Design), the SolarPower Summit Award, and a finalist in the Intersolar EES Award.
Commenting on the development, Jan Senn, CMO & Sales at EET stated, “Our vision is to make renewable energy simple, safe and reliable for everyone. We accomplish this by enabling individuals to use green energy where it is most crucial – in their own homes.
SolMate combines the highest quality, excellent user experience, and design into one user-friendly lifestyle product for every home. Transitioning to GaN helps us realize this vision, and we are currently exploring the integration of GaN transistors from EPC in other power converters as well.”
Stefan Werkstetter, VP of EMEA Sales at EPC, stated, “We are delighted that EET has chosen our EPC2204 eGaN FET for their SolMate green solar balcony product. Our commitment to delivering high-performance and efficient power conversion solutions aligns perfectly with EET’s mission to make renewable energy accessible and reliable for all. We look forward to continuing our partnership with EET and contributing to the advancement of sustainable energy solutions.”

Applied Materials, Inc. and CEA-Leti announced an expansion of their longstanding collaboration to focus on developing differentiated materials engineering solutions for several specialty semiconductor applications.
The joint lab, which represents CEA-Leti’s highest level of collaboration, aims to accelerate device innovations for Applied’s customers serving ICAPS markets (IoT, Communications, Automotive, Power and Sensors). Technology applications in those fields include photonics, image sensors, RF communications components, power devices and heterogeneous integration.
Demand for ICAPS applications and devices is being driven by industrial automation, the Internet of Things (IoT), electric vehicles, green energy and smart grid infrastructure, among other major high-growth markets. Projects at the joint lab will focus on developing solutions for a variety of materials engineering challenges to enable the next wave of ICAPS device innovation. The joint lab features several of Applied Materials’ 200mm and 300mm wafer processing systems and leverages CEA-Leti’s world-class capabilities for evaluating performance of new materials and device validation. Improvements in power consumption, performance and area/cost, along with faster time to market (PPACt™), will be key objectives of the joint team.
“CEA-Leti and Applied Materials aim to accelerate innovation and advance the roadmaps of a wide range of specialty semiconductor technologies,” said Aninda Moitra, corporate vice president and general manager of Applied Materials’ ICAPS business. “Our work at the joint lab builds upon more than a decade of successful collaboration and further strengthens our combined ability to enable faster time to innovation for ICAPS chipmakers.”
“For the past 10 years, Applied Materials and CEA-Leti have collaborated through multiple, specific joint development programs, which have set the stage for establishing our new joint lab,” said Sébastian Dauvé, the institute’s CEO. “Past projects included work in domains such as advanced metrology, materials for memory applications and optical devices, bonding techniques, materials deposition and film growth (PVD, CVD, ECD, Epitaxy) and chemical-mechanical planarization (CMP). Our results brought high value to both partners and to customers around the world, and we look forward to expanding our engagement with this new lab.”
“The joint lab, which is based at CEA-Leti, will host Applied Materials scientists and involve some of its latest-generation equipment,” Dauvé said. “In addition to developing differentiated technological solutions for Applied’s customers, the work performed at the joint lab will help overcome current technical hurdles in support of CEA-Leti’s internal R&D programs.”
