GaN Systems and Phihong debut highest-power-density gaming laptop power supply

GaN Systems Inc of Ottawa, Ontario, Canada (a fabless developer of gallium nitride-based power switching semiconductors for power conversion and control applications) and power supply company Phihong Technology have announced the debut of Phihong’s 280W GaN charger (claimed to be the industry’s highest-power-density power supply for gaming laptops). The new GaN charger is being showcased in GaN Systems’ booth #509 (Hall 9) at Power, Control and Intelligent Motion (PCIM) Europe 2022 in Nürnberg Messe, Nuremberg, Germany (10–12 May).

Phihong’s 280W GaN gaming power supply highlights a performance level that is claimed to lead the industry in an ultra-compact case size of 160mm x 69mm x 25mm and a 700g lightweight design. At 16W/in3 power density, the charger is 50% smaller and 30% lighter than legacy 280W gaming chargers. The 280W GaN charger is also highly efficient, with a 95% full load conversion efficiency and <0.2W no-load standby loss.

Featuring GaN Systems’ power semiconductors, Phihong’s 280W GaN gaming power supply combines a high-efficiency topology structure, zero voltage and zero current soft-switching technology, digital control.

GaN Systems says that its power semiconductors enable power supply manufacturers to deliver smaller, lighter-weight, cost-effective, reliable solutions. The advantages of GaN allow more efficient power density to power supplies while providing the higher power and faster charging times that are important to consumers.

“In this very mobile world, users want thin, sleek mobile devices and seek the same requirements for the chargers that go along with them. With GaN, gone are the days of the ‘brick’ power supply,” says GaN Systems’ CEO Jim Witham. “It’s great to see Phihong design in GaN Systems in their AC adapters to achieve the small size and high power demanded by laptop users.”

At PCIM, GaN Systems is showcasing Phihong’s 280W GaN charger together with an array of GaN chargers for smartphone and laptop charging, up to 4x smaller than conventional chargers ranging from 45W to 280W.
