[{"type":"text","content":"Next-gen semiconductor drives 135W fast charger, Lenovo and Navitas shine on Nasdaq\nEL SEGUNDO, Calif., May 12, 2022 (GLOBE NEWSWIRE) -- Navitas Semiconductor (Nasdaq: NVTS) – the industry leader in gallium nitride (GaN) power ICs - today officially announced that its next- generation GaNFast™️ power ICs with GaNSense™ technology have been used in Lenovo's newly-released Legion C135 GaN charger, and featured on the Nasdaq Tower in Times Square, New York. Lenovo’s Legion 5 and 5 Pro Gen 7 laptops are significant gaming machines, featuring AMD Rembrandt Ryzen 9 or Intel 12th-gen Alder Lake Core CPUs, AMD Radeon Vega or NVIDIA RTX GPUs, 32 GB of DDR5 memory, 1 TB of solid-state drive, up to 16” screens with 240 Hz refresh rates, and a mighty 80 Whr battery. GaN is a next-generation semiconductor technology that runs up to 20x faster than legacy silicon (Si) chips, and enables up to 3x more power or 3x faster charging in half the size & weight. GaNFast power ICs with GaNSense technology integrates power, drive, control, with additional autonomous-protection and loss-less current-sensing to deliver the simplest, smallest, fastest and now even-higher-power performance. The 135 W-rated GaNFast charger measures only 66 x 65 x 31 mm (133 cc) – 40% smaller than legacy chargers – so the C135 achieves a power density over 1 W/cc. The power conversion topology is a PFC stage followed by an isolating high-frequency, quasi-resonant (HFQR) flyback using Navitas’ NV6136A GaNFast power IC with GaNSense technology. This eliminates the system-current-sensing resistor, avoids a high-temperature ‘hot-spot’ and delivers an additional 10% of energy savings with increased system reliability. Peak charging-efficiency is over 92%, enabling the high power-density. The C135 adopts Lenovo's proprietary protocol to reach the full 135W rating and a 0-100% charge-time of only 65 minutes. Also equipped with universal, industry-standard protocols (USB-PD, USB-PPS and QC) at 100W and below, the C135 can also fast-charge any number of laptop, tablet, phone and audio models from Lenovo and any other manufacturer. Lenovo’s Chen LONG, PRC Consumer IP Product Marketing Manager said on the product launch: \"Navitas’ GaNFast power ICs have proven themselves at Lenovo with high performance and high quality since the 2020 launch of the 90W charger for the Lenovo Legion Pr...
