GaN Systems Introduces 50% Smaller 250 W AC to DC GaN Charger Design


GaN Systems has announced the availability of a new turnkey 250 W AC to DC GaN charger reference design. It features ultra-high-power density (16 W/in3) and up to 96 % peak efficiency in a low profile form factor. This latest reference design enhances GaN Systems’ portfolio of turnkey charger solutions for the consumer electronics market, enabling faster design cycles and roll-out of smaller, lighter, and more powerful and efficient chargers.

Laptop computers have become vital for work and personal use. Demand for more processing power, graphics capabilities, better audio, and more features are pushing new designs. And trends for higher performance, lighter-weight, and thinner laptop PCs will continue. To complement these trends, consumers want smaller, thinner chargers to match.

The reference design provides a complete solution to customers. It includes the fully assembled and tested charger with documentation. This best-in-class 250 W, 19 Vdc output charger offers an advanced multi-mode PFC plus synchronous rectification half-bridge LLC topology. It uses GaN Systems’ new 8 x 8 mm PDFN package GS-065-011-2-L transistor, ideal for applications such as notebook PC and gaming laptop PC chargers. The topologies implemented are cost-effective, reduce component count, and allow easy customization.

Key features of the 250 W reference design:

  • Ultra-slim design: <22 mm height
  • High-power density: 50 % size reduction, 16 W/in3
  • High efficiency: 96 % peak efficiency
  • Meets EN55032 Class B EMI and IEC62368-1 safety standards
  • Temperature rise below 45 ºC at 40 ºC ambient

“More customers are using GaN Systems’ reference designs to move quickly in the market,” says Paul Wiener, VP of Strategic Marketing at GaN Systems. “Mobility and portability are part of today’s lifestyles, driving the need for lighter and smaller devices, and I expect this 250 W turnkey adapter to continue the high pace of GaN Systems adoption in chargers and adapters.”
