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.”
