Innergie uses Rohm's EcoGaN in new charger


45W output USB-C charger C4 duo benefits from strategic partnership

Rohm has announced the adoption of its 650V GaN device (EcoGaN) in the C4 Duo, a 45W output USB-C charger from Innergie, a brand of Delta. a provider of IoT-based solutions headquartered in Taiwan.

The two companies been working together since 2022 to develop next-generation power semiconductors for power supply systems. One of the outcomes was the 650V GaN GNP1150TCA-Z HEMT, now used in Innergie’s new products.

The GNP1150TCA-Z has an integrated ESD protection element. According to Rohm, this improves ESD breakdown tolerance by approximately 75 percent over standard GaN HEMTs. The improvement in application reliability ultimately led its adoption in the charger.

Jason Chen, general manager, Innergie said: "The C4 Duo is the first model from Innergie’s 'One for All Series' adapters to use Rohm’s GaN devices, and we expect more models to adopt this state-of-the-art technology. We believe that, by strengthening our collaboration with Rohm, we will be able to provide customers adapters featuring higher power efficiency and capability, but with much smaller product size.”
