    EPC Introduced 1 mOhm GaN FET

    1 Min Read

    EPC introduced the 100 V, 1 mOhm EPC2361. This is the lowest on-resistance GaN FET on the market offering double the power density compared to EPC’s prior-generation products.

    The EPC2361 has a typical RDS(on) of just 1 mOhm in a thermally enhanced QFN package with exposed top and tiny, 3 mm x 5 mm, footprint. The maximum RDS(on) x Area of the EPC2361 is 15 mΩ*mm2 – over five times smaller than comparable 100 V silicon MOSFETs.

    With its ultra-low on-resistance, the EPC2361 enables higher power density and efficiency in power conversion systems, leading to reduced energy consumption and heat dissipation. This breakthrough is particularly significant for applications such as high-power PSU AC-DC synchronous rectification, high frequency DC-DC conversion for data centers, motor drives for eMobility, robotics, drones, and solar MPPTs. 

    “Our new 1 mΩ GaN FET continues to push the boundaries of what is possible with GaN technology, empowering our customers to create more efficient, compact, and reliable power electronics systems,” comments Alex Lidow, EPC CEO and co-founder.

    EPC Introduces Three Evaluation Boards

    2 Min Read

    EPC introduces three evaluation boards – EPC9179, EPC9181, and EPC9180 – featuring pulse current laser drivers of  75 A, 125 A, and 231 A , showcasing EPC’s AEC-Q101 GaN FETs. These FETs; EPC2252, EPC2204A, and EPC2218A are 30% smaller and more cost-effective than their predecessors. Designed for both long and short-range automotive lidar systems, these boards expedite solution evaluation with varied input and output options.

    All boards share identical functionality, differing only in peak current and pulse width. Utilizing a resonant discharge power stage, they employ a ground-referenced GaN FET driven by LMG1020 gate driver. The GaN FET’s ultrafast switching enables rapid discharge of a charged capacitor through the load’s stray inductance, enabling peak discharge currents of tens to hundreds of amps within nanoseconds.

    The printed circuit board is designed to minimize power loops and common source inductance while offering mounting flexibility for laser diodes or alternative loads. To enhance user-friendliness, all boards ship with EPC9989 interposer PCBs, featuring various footprints to accommodate a variety of laser diodes or other loads. Customers can choose one that meets their needs to evaluate the GaN solutions.

    The EPC9179/81/80 boards are designed to be triggered from 3.3V logic or differential logic signals such as LVDS. For single-ended inputs, the boards can operate with input voltages down to 2.5 V or 1.8 V with a simple modification. Designing an automotive lidar system is complex, and finding a reliable solution is challenging. The purpose of these evaluation boards is to simplify the evaluation of powerful GaN-based lidar drivers that switch faster and deliver higher pulse current than other semiconductor solutions. For technical details, EPC offers full schematics, bill of materials (BOM), PCB layout files, and a quick start guide on EPC’s website.

    “To meet the growing demand for automotive lidar, these cost-effective boards, featuring our latest AEC products, streamline evaluation, reducing time-to-market with exceptional switching performance,” said Alex Lidow, CEO, and co-founder of EPC.

    Efficient Energy Technology Selects EPC’s EPC2204 eGaN for SolMate

    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.”
