EPC GaN FETs Enable 4 kW High-Efficiency Buck-Boost Converter Reference Design

EPC2361 eGaN® FETs deliver high-current, low-loss switching in a 36 V to 65 V input, 48 V output platform

EL SEGUNDO, CA, UNITED STATES, October 20, 2026 /EINPresswire.com/ — Efficient Power Conversion (EPC), a leader in enhancement-mode gallium nitride (eGaN^®) power devices, today announced the use of its EPC2361 100 V eGaN FETs 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 36 V to 65 V input and delivering 48 V output. The platform supports up to 4 kW of output power and achieves typical efficiencies of 98.5% at 36 V and 48 V input and 98.8% at 65 V, demonstrating the high-efficiency power conversion enabled by EPC’s GaN technology.

The EPC2361 is a 100 V, 133 A enhancement-mode GaN transistor featuring a typical 0.75 mΩ on-resistance and a compact 3 mm × 5 mm 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 10 ns based on the EPC2361 GaN FET parameters, helping 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,” said Alex Lidow, CEO and co-founder of EPC. “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. 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. It’s 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.
