Navitas Semiconductor of Torrance, CA, USA says that its next-generation GaNFast power ICs have been selected for the ‘in-box’ 125W charger of Motorola’s latest flagship smartphone (the X30 Pro), providing a charge from 1% to 50% in just 7 minutes.
The X30 Pro is said to be the world’s first to feature a 200MP main camera, and has a Snapdragon 8+ Gen 1 SoC, plus a 6.7-in OLED display with 144Hz refresh rate. To support this performance, the X30 Pro has a 4610mAhr battery, and 125W ultra-fast wired charging.
High-speed GaNFast power ICs enable the lightweight 138g ultra-fast charger to measure only 55.6mm x 55.7mm x 28.4mm (88cc) and achieve 1.42W/cc power density, enhancing portability. GaNFast ICs integrate GaN power and drive, plus control, protection and sensing to enable up to 3x faster charging with up to 40% energy saving in only half size and weight, compared with legacy silicon solutions. In this charger, two NV6134A GaN ICs are used in CrCM boost power factor correction (PFC) and HFQR DC-DC topologies.
The 125W GaN charger is designed by China-based Aohai Technology specifically for the Motorola X30 Pro. “Navitas has always been a trust-worthy partner,” comments Cuisi Kuang, senior VP at Aohai. “Navitas’ GaNFast power ICs are fast and reliable, easy-to-use, and we can complete our R&D with a faster speed and higher success rate,” he adds.
“By working hand-in-hand with Navitas and Aohai Technology, we are able to utilize GaN and speed up the charging capability of Motorola’s smartphones to a new level,” comments Jin Chen, general manager of Smartphone business unit, Lenovo China. “We look forward to collaborating further with Navitas and Aohai Technology, to break more records in charging speed, and offer a convenient and ultra-fast-charging experience,” he adds.
“This time, Motorola, Navitas and Aohai Technology’s new collaboration reached a new, benchmark 125W fast-charging solution on the new X30 Pro,” notes Charles (Yingjie) Zha, VP & general manager of Navitas China: “Navitas will continue to push the innovation of GaN technology to empower Motorola’s charging roadmap.”
