Navitas and Lenovo partner on first GaNFast 90W fast charger for e-sports mobile phones
Navitas Semiconductor Inc of El Segundo, CA, USA says that the fastest, most powerful charger for Legion e-sports, using GaNFast power ICs, has been launched into mass production and supplied ‘in-box’ with every Lenovo Legion phone.
Founded in 2014, Navitas introduced what it claimed to be the first commercial gallium nitride (GaN) power ICs. The firm says that its proprietary ‘AllGaN’ process design kit (PDK) monolithically integrates GaN power field-effect transistors (FETs) with GaN analog and logic circuits, enabling faster charging, higher power density and greater energy savings for mobile, consumer, enterprise, eMobility and new energy markets.
GaN technology enables the 90W dual USB-C output charger to deliver 40% more power and charge 25% faster than previous best-in-class hardware, it is claimed.
Measuring only 66mm x 62mm x 28mm (115cc), the 90W Legion fast charger can charge a 5000mAh battery to 100% in only 30 minutes, enabled by GaNFast technology. Running 20 times faster than the traditional silicon, it improves the power by three times, making the charging speed three times faster, in half the size and weight of silicon chargers.
“It is a great pleasure for us to establish long-term cooperation and explore more new possibilities with Navitas Semiconductor,” says Jin Chen, general manager of Lenovo China’s Cellphone Business Department.
“The cooperation with Lenovo is a great milestone because Lenovo is not only a top phone manufacturer but also a top PC device manufacturer,” says Yingying (Charles) Zha, VP & general manager of Navitas China. “GaNFast power ICs are a single chip integrating GaN field-effect transistor (FET), GaN digital and GaN analog circuits. It rapidly promotes the commercialization of the new generation of high-frequency, high-efficiency and high-power-density power converters,” he adds.
