Power Integrations buys Odyssey Semiconductor GaN assets

Power Integrations has announced an agreement to acquire the assets of Odyssey Semiconductor Technologies, a developer of vertical gallium-nitride (GaN) transistor technology.

The transaction is expected to close in July 2024, after which all key Odyssey employees are expected to join Power Integrations’ technology organization. The experience of the Odyssey team in high-current vertical GaN will augment and accelerate efforts toward cost parity with silicon MOSFETs.

The acquisition supports the company’s ongoing development roadmap for its proprietary PowiGaN™ technology, which is featured in many of the company’s product families including InnoSwitch™ ICs, HiperPFS™-5 power-factor-correction ICs and the recently launched InnoMux™-2 family of single-stage, multiple-output ICs. The company introduced 900- and 1250-V versions of PowiGaN technology and products in 2023.

Commented Dr. Radu Barsan, Power Integrations’ vice president of technology: “Power Integrations has been at the forefront of GaN development and commercialization since we began shipping products with PowiGaN technology in 2018. We are executing on an ambitious roadmap that includes driving toward cost parity with silicon MOSFETs and expanding the voltage and power capabilities of PowiGaN. Our goal is to commercialize a cost-effective high-current and high-voltage GaN technology to support higher-power applications currently served by silicon carbide (SiC), at a much lower cost and higher performance enabled by the fundamental material advantages of GaN over SiC. The experience of the Odyssey team in high-current vertical Gallium Nitride will augment and accelerate these efforts.”

Added Dr. Richard Brown, Odyssey co-founder and CEO: “The Odyssey team and I are excited to join Power Integrations in accelerating their GaN technology roadmap. As the first company to commercialize high-voltage GaN, Power Integrations continues to lead the industry in driving the technology forward in terms of cost, voltage and current, as well as the design of system-level products that take full advantage of the capabilities of GaN.”
