Consumer power supplies, datacom/telecom and automotive applications are driving the GaN market to a $2B business

High volumes in the GaN market are today a reality. GaN fast chargers are growing rapidly in the handset market. Since 2020, Yole has seen an increasing number of fast chargers featuring GaN devices from several players, like Power Integrations, Navitas, and GaN Systems. Now Innoscience also contributes to this market with high volumes. The consumer power supply market will be worth more than $915.6M by 2027, with a Compound Annual Growth Rate for 2021-2027 (CAGR2021-2027) of 52%. For datacom/telecom, we expect an increase in GaN penetration in the mid-term as regulations become stricter. The interest in adopting 48V-Point-Of-Load systems in datacenters to reduce power consumption and cabling volume will favor GaN for low-voltage applications. An increasing number of power suppliers are adopting GaN in their systems. Transphorm, EPC, Texas Instruments, Infineon, and GaN Systems have all announced several design wins. Therefore, the GaN market for datacom/telecom is expected to have a CAGR2021-2027 of 69%, becoming worth more than $617.8M by 2027. At a lower penetration level, automotive DC-DC converters and On-Board Chargers (OBCs) will be part of the next wave of growth during the forecasted period. According to feedback we have received, there are ever more collaborations between GaN device players, who are accelerating the automotive qualification of their products, and the Tier-1 and OEMs, who are evaluating automotive GaN solutions. The GaN automotive market is expected to exceed $227M by 2027, with a CAGR2021-2027 of 99%.

This report details the penetration of GaN devices in different applications from the system point of view, and forecasts that penetration from device to wafer level with different granularities.

Dynamic supply chain with new entrants and significant investments

Since the release of our last GaN Power 2021 report, Yole has witnessed the entry of new players to the supply chain. Notably, Rohm is offering a 150V GaN product for telecom/datacom applications. BelGaN, a new GaN foundry based in Belgium, has recently acquired onsemi’s fab in Oudenaarde. And on the fundraising front, Navitas went public through a Special Purpose Acquisition Company (SPAC) business combination after an agreement valued at $1.04B with Live Oak Acquisition Corp.
Focusing on the Chinese ecosystem, we are seeing ever more investment from GaN players supported by the government. It is noteworthy that Innoscience is investing more than $400M to expand its 10k 8-inch wafer per month capacity to 70k wafers per month by 2025. A domestic supply chain for GaN power is well developed, especially for the consumer market.
The transition to the 8-inch platform and the consolidation of the supply chain with more players at each level are driving towards lower manufacturing cost. Especially at the epitaxy step, which constitutes the biggest part of a GaN device cost structure. In fact, one of the big questions is also around the use of in-house epitaxy and outsourced epitaxy for future high volumes.

We invite you to read our Power GaN 2022 report for comprehensive analyses of market dynamics, supply chain evolution, and the latest technology trends for various applications.
