Navitas Partner with Lenovo to Launch 130 W GaNFast Charger

712370

Navitas Semiconductor has announced that Lenovo has launched the YOGA CC130, their fifth GaNFast charger, with dual USB Type-C outputs and high power 130 W capability. Either Type-C output can provide 100 W for large laptops and fast-charging smartphones, with a combined 130 W of dynamically shared total power when both ports are used. Fast-charging communication protocols include USB-PD, Qualcomm QC 3.0, and USB-PPS. By exploiting the high-speed, high-efficiency performance of GaNFast technology, the dual-output CC130 measures only 71 x 71 x 30 mm (151 cc) to achieve a power density of 0.85 W/cc at a lightweight 265 g. This represents up to 40 % size and 45 % weight savings compared to single-port legacy silicon adapters.

Gallium nitride (GaN) is a next-generation semiconductor technology that runs up to 20x faster than legacy silicon chips. Navitas' proprietary GaN power ICs integrate GaN power (FET) and GaN drive plus control and protection in a single SMT package. These 'GaNFast' power ICs become easy-to-use, high-speed, high-performance 'digital-in, power-out building blocks and deliver up to 3x faster charging in half the size and weight, and with up to 40 % energy savings compared with earlier silicon solutions. An estimated $13.1 billion electrification opportunity includes mobile fast chargers and adapters, data centers, solar energy, and EV.

The CC130 dual-port GaN adapter uses GaNFast power ICs in two high-speed, 'soft-switching topologies to achieve the impressive size and weight reductions. The first is a CrCM boost power-factor correction (PFC) circuit, using Navitas NV6117 (120 mOhm) GaN power ICs to convert rectified AC power to a stable 400 V DC rail. This is followed by a high-speed, isolating, LLC DC-DC stage with two NV6115 (170 mOhm) ICs to efficiently step down the voltage to approximately 20 V for the USB-PD output stages. Both GaNFast ICs are rated at 650/800 V, up to 2 MHz switching frequency in space-saving 5 x 6 mm QFN SMT packages. Thanks to the integration of GaN FET, drive, protection, and control, no external drivers are needed which saves PCB space, and high-speed (switching-frequency) operation shrinks the size and cost of transformers, filters, and capacitors.

Reliability is a critical specification, and the YOGA CC130 adapter has passed 81 Lenovo professional-grade laboratory tests, supports ESD protection, and passed the long-term use test of 8,700 hours at full power.

Lin Lin, Director of Notebook Planning for Lenovo's Consumer Business in China, said "This generation of CC130 is equipped with Navitas GaNFast technology, which has enabled faster-charging speed, higher efficiency, lower temperature, and smaller size."

The CC130 was jointly supervised by Lianbao Electronic Technology and designed and built for Lenovo by Luxshare, headquartered in Dongguan City, Guangdong. "At our core, we're a technology company, and for power electronics, this means the research, development, and production of GaN fast chargers to stay at the forefront of the industry," said Fu Qiang Wang, Power R&D Director for Luxshare. "Luxshare chose Navitas' GaNFast power ICs to build the YOGA CC 130 and enable the consumer's dream product. We firmly believe in the future potential of gallium nitride charging technology as a focus for Luxshare's continuous research and development, to become a leading pioneer in the industry.

"After the successful YOGA CC65, Navitas is honored to support Lenovo with the YOGA CC130 at twice the power," said Stephen Oliver, Vice President of Corporate Marketing and Investor Relations. "The CC130 will bring a faster, lighter, more powerful, and more portable charging experience to Lenovo consumers. Navitas will continue to support Lenovo and Luxshare to develop further generations of GaN fast chargers, and to promote the innovation and development of the high-performance fast-charge industry, to benefit consumers worldwide."
