What Efficient Power Conversion does

Efficient Power Conversion Corporation (EPC), founded in 2007 and headquartered in El Segundo, California, is a privately held fabless semiconductor company that designs and sells enhancement-mode Gallium Nitride (eGaN) field-effect transistors and integrated circuits for power conversion. Its portfolio spans 15V to 350V in chip-scale and QFN packaging and is organized around discrete GaN FETs, monolithic ePower Stage half-bridge and 3-phase ICs that integrate FETs with gate drivers, eToF laser driver ICs for lidar and 3D sensing, automotive AEC-qualified devices, and radiation-hardened GaN products (via subsidiary EPC Space). The company has iterated through seven device generations, most recently with Generation 7 (EPC2366) claiming to outperform silicon MOSFETs in the 15V–40V range for the first time and the EPC2367 100V FET delivering 1.2 mΩ on-resistance for 48V intermediate bus architectures. Reliability is evidenced across 18 published testing phases spanning gate reliability, overvoltage stress, current density, and thermomechanical wear-out.

EPC sells primarily through authorized distributors — Digi-Key and Mouser Electronics globally, Arrow Electronics in Asia Pacific, and dozens of regional specialists — augmented by direct factory sales representatives and Field Applications Engineers in the Americas, EMEA, China/Hong Kong, Taiwan/SE Asia, South Korea, and Italy. Unit pricing is publicly listed (FETs from approximately $0.52 to $5.58 at 2.5Ku; integrated ICs such as the EPC33110 at $12.38; evaluation boards such as the EPC91121 at $670 and EPC91202 at $500). The company pursues a hybrid go-to-market combining self-serve product-led growth (parametric selection tools, reference designs, GaN First Time Right design support, GaN University, GaN Talk blog/podcast) with enterprise field sales targeting design-in wins in automotive, AI data center, robotics, industrial, aerospace/defense, consumer electronics, MedTech, and communications end markets.

EPC's strategic positioning in 2025–2026 emphasizes AI infrastructure power (a 5 kW GaN AC/DC reference design for AI servers, NVIDIA MGX / 800V rack engagement), humanoid robotics (a string of joint-inverter evaluation boards and 100V integrated power-stage ICs), and supply-chain scaling via a February 2026 technology licensing and second-sourcing agreement with Renesas Electronics and a May 2026 global distribution expansion with Mouser. Founder and CEO Alex Lidow is the co-inventor of the HEXFET power MOSFET, lending the leadership team deep compound-semiconductor credibility. The company employs 51–100 staff, operates multiple regional sales offices, and maintains multilingual digital presence (English, Simplified Chinese, Traditional Chinese, Japanese).
