ROHM and Delta Electronics Form a Strategic Partnership on Developing Power Devices for Power Supply Systems

Global semiconductor supplier ROHM, together with Delta Electronics, a world-class power supply manufacturer, have entered into a strategic partnership to develop and mass produce next-generation GaN (gallium nitride) power devices.

Combining Delta’s power supply device development technology cultivated over many years with ROHM’s market-proven power development and manufacturing expertise will make it possible to develop 600V breakdown voltage GaN power devices optimized for a wide range of power supply systems.

ROHM has already established a mass production system for 150V GaN HEMTs featuring a breakthrough 8V gate withstand voltage in March 2022. This will allow ROHM to expand its new lineup of EcoGaNTM for power circuits in IoT communication and industrial equipment (i.e. base stations, data centers) while further improving device performance.

Improving the efficiency of motors and power supplies, which are said to account for the most of the world’s electricity consumption, has become a significant hurdle to achieving a decarbonized society. As power devices hold the key to improving efficiency, the adoption of new materials such as SiC and GaN is expected to further increase the efficiency of power supplies. ROHM and Delta have been engaged in technological exchanges and building a cooperative relationship in the development of various applications for many years, and through this partnership both companies will develop and mass produce the industry’s most advanced GaN power devices that maximize GaN performance to accelerate power technology innovation and contribute to achieving a sustainable society.
