300 W Adapter Reference Design From GaN Systems And ON Semiconductor Highlights GaN Innovation And Performance In Consumer Devices

New solution is ideal for high efficiency, ultra-high-power density adapter applications for televisions, gaming notebooks and consoles, and industrial and medical devices.

Ottawa, ON and Phoenix, AZ (GLOBE NEWSWIRE) - GaN Systems, the global leader in GaN (gallium nitride) power semiconductors and ON Semiconductor, a world-leading supplier of power semiconductor ICs, today announced the availability of the world’s highest power density 300 watt AC Adapter Reference Design using GaN Systems’ 650 V, 15 A GaN E-HEMTs and multiple award-winning ON Semiconductor Controller and Driver ICs: NCP51820, NCP13992, NCP1616, and NCP4306.

This complete system reference design is highly versatile and low cost, allowing designers to easily develop and bring to market ultra-high power density adapters for various applications in HDTV power supplies, gaming notebook and console adapters as well as ultra-small power supplies for industrial and medical devices.

The kit and application note provide detailed technical information including schematic, PCB layout, and BOM (bill of material) files, and EMI and efficiency data. The kit hardware has complete PFC, LLC, and secondary stages, and features a high-efficiency synchronous PFC which meets CoC T2 benchmark, a highly-versatile low-cost 2-Layer design, and universal input with 19 V Output at 340 W peak. System designers using this GaN-based reference design can reach power densities up to 32 watts per cubic inch.
