EPC’s GaN FETs enable 4kW high-efficiency buck-boost converter reference design
Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA — which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) and integrated circuits for power management applications — says that its EPC2361 100V eGaN FETs have been used in a high-performance buck-boost converter reference design from Analog Devices Inc (ADI).
The design demonstrates how GaN technology can enable efficient, high-current power conversion for demanding industrial, telecom, battery charging, and other high-power applications.
The EVAL-LT7930-AZ combines the LT7930 controller with EPC2361 GaN FETs in a dual-phase, interleaved buck-boost converter operating from 36V to 65V input and delivering 48V output. The platform supports up to 4kW of output power and achieves typical efficiencies of 98.5% at 36V and 48V input and 98.8% at 65V, demonstrating the high-efficiency power conversion enabled by EPC’s GaN technology.
The EPC2361 is a 100V, 133A enhancement-mode GaN transistor featuring a typical 0.75mΩ on-resistance and a compact 3mm x 5mm package. Its ultra-low conduction losses, low gate charge, and absence of reverse recovery make it well suited to high-current, high-frequency power conversion applications.
A key element of the reference design is the ability to optimize the switching behavior specifically for GaN. The power-stage controller provides gate drivers optimized for GaN FETs and programmable dead-time control. On the evaluation platform, the dead time is set to 10ns based on the EPC2361 GaN FET parameters, helping to minimize reverse-conduction losses while maintaining safe switching operation.
“High-power conversion increasingly requires a combination of efficient control architectures and low-loss power devices,” says CEO & co-founder Alex Lidow. “The EVAL-LT7930-AZ demonstrates how EPC’s EPC2361 GaN technology can be combined with the ADI LT7930 controller to deliver a compact, highly efficient multi-kilowatt buck-boost platform,” he adds. “This type of collaboration helps power designers move GaN from individual devices into complete high-performance power systems.” The EPC2361 is designed for applications including high-power AC–DC power supplies, high-frequency DC–DC conversion, data-center power systems, motor drives, robotics, drones, and solar MPPT.
The EPC2361 is available through EPC’s global distribution network, Digi-Key, and Mouser. EPC provides comprehensive design resources, including device documentation, models, and evaluation hardware, to help engineers evaluate and integrate the EPC2361 into their designs.
