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 watts AC Adapter Reference Design using GaN Systems’ 650 V, 15 A GaN E-HEMTs and multiple award-winning ON Semiconductor Controller and Driver ICs: NCP51820NCP13992NCP1616, 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 provides 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 the 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.
