The 650V GaN device (EcoGaN™) of the world-renowned semiconductor manufacturer ROHM Co, Ltd (hereinafter referred to as "Rohm") has recently been used by Delta Electronics (Delta Electronics, Inc., hereafter referred to as "Delta") Innergie brand 45W output AC Adapter "C4 Duo" adopted. Delta, as a global supplier of green solutions based on IoT technology, has introduced ROHM's GaN devices into its Innergie brand AC adapter to improve product performance and reliability and achieve product miniaturization.

In the process of promoting a carbon-free society, the improvement of energy efficiency is particularly important. Because processing high-power devices brings significant power consumption, relevant manufacturers are taking steps to accelerate the pace of energy conservation. GaN (gallium nitride) devices have become the first choice of many manufacturers as they can work efficiently.

Rohm names devices using GaN under the "EcoGaN™" brand and is continuously expanding its product lineup. Despite GaN's potential, it can be challenging to process. ROHM has been committed to promoting "ease of use" product development and providing related solutions. In this regard, Rohm has begun mass production of 150V voltage-resistant GaN HEMTs, and will begin mass production in 2023 to achieve the industry's ultra-high performance 650V voltage-resistant GaN HEMTs.

Innergie (Delta's brand) General Manager Jason Chen said: "The technological progress of GaN power devices has attracted great attention from the global electronics industry. Over the past few years, exchanges between the two parties have continued to deepen, and in 2022 they reached an agreement on power devices for power systems. entered into a strategic partnership. As a result of technical exchanges between the two parties, Rohm’s 650V GaN

HEMT "GNP1150TCA-Z" provides support for Innergie's new products. "C4 Duo" is the first product in the "One for All series" to use ROHM's GaN devices, and it is hoped that it can be used in more models of products in the future. We believe that by continuing to strengthen cooperation with ROHM, we will be able to provide AC adapters with higher output power and more powerful functions. "

Yuhei Yamaguchi, General Manager of the Power Stage Product Development Department of the Power Supply LSI Business Unit of ROHM LSI Business Headquarters, said: "It is a great honor for ROHM's EcoGaN™ to be adopted by Delta, a global leader in power management and thermal countermeasures, for AC adapters. ROHM is adopting Improving the performance of power semiconductors and analog technology that can build better topologies help Delta improve the power conversion efficiency of its high-power power supply devices.

In addition, the two companies have similar business visions in realizing a carbon-free society and a digital society. The two companies have established a solid cooperative relationship by leveraging Delta's advantages in power circuit design and ROHM's advantages in devices, ICs and other products. , which also contributed to this successful adoption. It is hoped that both parties will use the deepening cooperative relationship to continue to promote the development of smaller, more efficient chargers and other products, and contribute to enriching people's lives.
