Increasing adapter efficiency with GaN

News
Infineon and Chicony Power collaborate on GaN-based PD3.1 notebook adapter solutions to improve efficiency

Power supply maker Chicony Power Technology is increasing the performance of its latest PD3.1 notebook adapter series using Infineon's CoolGaN and CoolMOS technology .

The result, according to the companies, is that Chicony Power's new adapter series can provide around 30 percent increase in power density due to the new topology . Moreover, the new power adapter series can deliver up to 240W compared to the 100W defined in USB 3.0 and charges high performance notebooks such as gaming computers and multimedia workstations via USB-C power delivery. The new power adapter series can be used as a universal power supply for multiple electronic devices.

“We use our unique expertise in GaN technology, in applications and system solutions to make high performance computing more efficient and more mobile,” said Adam White, president of Infineon’s Power and Sensor Systems Division. “We are happy that, together with Chicony Power and our CoolGaN technology, we can realise the new power design capability for PD3.1 adapters, so that every user can easily contribute to decarbonising the way we work with computers – without compromising on mobility for the sake of performance.”

“Infineon is an excellent partner for us in energy conversion and energy efficiency,” said Yang Wang, VP R&D of Chicony Power. “Power and size are key points for mobile workers. GaN and silicon semiconductors from Infineon are the perfect match to increase power density and reduce losses.”
