Navitas and Powerland partner on thinnest, lightest 50W GaNFast charger
Gallium nitride (GaN) power integrated circuit firm Navitas Semiconductor of El Segundo, CA, USA and Dublin, Ireland says that its GaNFast gallium nitride (GaN) ICs are powering OPPO’s new 50W ultra-thin and ultra-fast ‘League of Legions’ limited-edition fast charger. This ‘collectable’ version of OPPO’s ‘cookie’ charger has a thin and light body and a ‘lanyard’ charging cable.
GaN runs up to 20x faster than silicon and enables up to 3x more power, 40% energy savings and 3x faster charging in half the size and weight, says Navitas. GaNFast power ICs integrate GaN power and drive plus protection and control to deliver simple, small, fast and efficient performance, the firm says. Over 30 million GaNFast power ICs have been shipped with zero reported field failures.
The OPPO cookie charger uses two 2MHz-rated NV6115 GaNFast ICs in an active-clamp flyback (ACF) architecture with zero-voltage and zero-current switching for the highest efficiency. The low-profile form-factor is achieved using a high-frequency planar transformer. At only 82mm x 39mm x 10.5mm (33cc) in size and weighing just 55g, the OPPO cookie is claimed to be the thinnest, lightest 50W fast-charger.
“GaN is now once again integrated into this charger that has attracted much attention from mobile game fans. This charger brings consumers a light and fast charging experience,” says OPPO’s chief charging technology scientist Jeff Zhang.
The ‘cookie’ charger was designed by Powerland Technology. “Powerland has always insisted on integrating excellent innovative technology like GaNFast power ICs with rich product-development experience, design and production,” says the firm’s co-founder Dr Qiu Yang. “The 50W ‘cookie’ charger is the crystallization of our continuous innovation. We look forward to continuing our cooperation with OPPO and Navitas Semiconductor,” he adds.
“Our joint goal is to continue to explore gallium nitride’s charging potential, to create smaller, lighter, greener and more convenient charging,” states Charles (Yingjie) Zha, VP & general manager of Navitas China.
