Founded in November 2007, Efficient Power Conversion Corporation (EPC) is a fabless semiconductor company headquartered in El Segundo, California, USA. The company specializes in the design, development, marketing, and sales of enhancement-mode gallium nitride (GaN) power management devices. EPC was the first to introduce enhancement-mode GaN-on-silicon transistors, branded as eGaN® FETs, revolutionizing power conversion efficiency. Its product portfolio includes discrete eGaN FETs, integrated circuits, and power modules that deliver significantly higher performance than traditional silicon power MOSFETs. These components enable higher switching frequencies, smaller form factors, and lower system costs in applications such as DC-DC converters, lidar, motor drives, and RF envelope tracking. EPC serves markets including data centers, automotive electronics, telecommunications, consumer electronics, and industrial systems. The innovative eGaN technology offers voltage ratings from 15 V to 200 V, providing faster switching, smaller die sizes, and superior thermal management. By leveraging mature silicon foundries, EPC combines the high performance of GaN with the scalability and reliability of silicon manufacturing. With over a decade of expertise, EPC is a leading provider of GaN power semiconductors, driving the industry toward more energy-efficient and compact power solutions. The company maintains a global presence, offering comprehensive design support and reference designs to accelerate GaN adoption.
