World’s Smallest GaN Chargers

Released at APEC this week!

GaN Systems, has announced the world’s smallest 65W and 100W GaN chargers offering the highest efficiency and best power density.

These groundbreaking chargers will be displayed in the GaN Systems booth #1324 at the 37th annual Applied Power Electronics Conference (APEC) in Houston.

65W AC-DC charger features:

  • Cased dimensions of 30.5 x 35.0 x 46.6mm
  • Highest efficiency at >94.5% @115Vac and >95% @230Vac
  • Highest power density at >22W/in3

100W AC-DC charger features:

  • Cased dimensions of 28.6 x 44.0 x 35.0 x 67.0mm
  • Highest efficiency at >94.5% @115Vac and >94.5 % @230Vac
  • Highest power density at >20W/in3

“These new GaN chargers are truly game-changers for the industry. Not only are they the smallest GaN chargers, but they also demonstrate a higher level of efficiency,” said Ionel (Dan) Jitaru, Rompower founder and CEO. “The technology advances in these chargers meet the newest demands in fast-charging applications where charger solutions must be small, cost-effective, and thermally efficient.”

Underpinning Rompower’s achievements in size and performance is GaN technology, which is quickly replacing traditional silicon transistors used in legacy chargers and adapters.

Strong growth from the consumer electronics industry from smartphones, PCs (desktops, notebooks, and workstations), and other personal devices is driving demand for chargers. Worldwide sales grew 6% in smartphones alone, with 1.4 billion phones sold in 2021, and global PC market shipments increased to 341 million units in 2021, 15% higher than in 2020, with revenues passing US$250 billion.

GaN transistors allow chargers to operate more efficiently, resulting in significantly less power loss and heat. This enables the system components to be smaller and closer together, resulting in smaller, sleeker chargers with more power than larger models. The GaN Systems transistors can be switched at high frequency for maximum efficiency and power density, making it ideal for charging applications.

“GaN is revolutionizing the consumer and industrial charger markets by reducing size up to 4X while delivering on consumers’ insatiable need for fast-charging. We are proud to partner with industry leaders from Dell to Harman to Samsung, leading the charge for GaN in consumer markets. Today’s collaboration with Rompower is the latest milestone on that journey and showcases GaN technology innovation at its best,” said Jim Witham, GaN Systems CEO.
