Navitas power bank Semiconductors today announced that OPPO, the world’s leading mobile phone manufacturer, has adopted its gallium nitride (GaNFast) power IC to manufacture the world’s smallest, thinnest and lightest 50W fast charger. The size of the charger is only 82x39x10.5 mm (34 cc) and the weight is only 60g. This is the first time in the industry that a fast charger that is as thin as the mobile phone itself has appeared. OPPO Mini charger provides 50W full power through OPPO’s first SuperVOOC fast charge protocol or USB-C programmable power supply (PPS) specification. It is very flexible and can charge smart phones, tablets and many laptops. In addition, it is as big as the popular Want Want Senbei, so many people call it a “biscuit” charger.

Navitas Helps OPPO Achieve Its Dream: the Smallest, Thinnest, Lightest and Most Versatile Fast Charger-askpower

On July 15, Zhang Jialiang, OPPO’s chief charging technology scientist, released a 50W Mini ultra-flash charger. He said: “For many years, the use of gallium nitride devices to drive transformers to very high frequencies has been the dream of all technicians. Gallium nitride devices will trigger a technological revolution in the power supply field.”

Gallium nitride (GaN) is a new generation of semiconductor technology. It runs 20 times faster than the old slow silicon (Si), and can achieve 3 times the power, that is, in the case of halving the volume and weight, the charging speed Can be increased by 3 times. Navitas GaNFast power IC integrates GaN power supply, GaN analog and GaN logic circuits on the same chip, achieving faster, reliable and efficient operation.

The high speed performance of GaN fast power IC of 50W Mini charger opens the door to a new circuit topology – “pulse type” flyback active clamp (ACF). It can withstand a wide input voltage range while maintaining a stable output to charge the mobile phone battery. The designer can remove 40% of the total volume of the electrical “large capacity capacitor” from the system. In addition, the operation speed is 16 times faster than that of the traditional charger, which means that the 50 kHz “wound” traditional transformer with a height of more than 20 mm can be replaced by a new planar transformer with a high speed of 800 kHz and 8 mm, which is extremely small in size and light in weight.

The new topology also allows oppo’s unique “direct charging” mode to reduce the wear mechanism and extend the life of mobile phone batteries.

“The 50W Mini charger is a model of a new generation of fast chargers. The combination of new materials, new architecture and new component technology has brought a revolution in power electronics technology,” said Steve, vice president of Navitas marketing and investor relations Oliver added, “our Gan fast chargers have gone far beyond the category of high-quality accessories and are now committed to the market of high volume, high cost performance and high performance The fate of the old, slow silicon chip is doomed. ”

About OPPO:

Oppo launched its first “smiling face mobile phone” in 2008, which started the journey of exploring and leading technology to the United States.
