Professional magazine and portal dedicated to electronics EPC GaN FETs Enable 4 kW High-Efficiency Buck-Boost Converter Reference Design
Author: Jan Robenek
Efficient Power Conversion announced the use of its EPC2361 100 V eGaN FETs in a high-performance buck-boost converter reference design from Analog Devices. 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 (more info).
