Navitas Semiconductor, a developer of gallium nitride (GaN) power ICs, has announced that its next-generation GaNFast power ICs with GaNSense technology have been selected to power vivo’s newly-released, first folding-screen flagship ‘X Fold’ in-box 80W flash charger.

The vivo X Fold adopts a high-capacity 4,600 mAhr dual-battery solution charging 0-50% in 17 minutes, and is fully-charged to 100% in only 37 minutes. The X Fold features multiple technological innovations, with Qualcomm Snapdragon 8+, 120 Hz refresh rate, 3D ultrasonic dual-screen fingerprint access and the world's first 300,000-fold TUV reliability certification.

As the first in-box GaN charger for a foldable phone, the dual-output 80W USB-C charger supports vivo’s proprietary fast-charge protocol and industry-standard USB-PD, with simultaneous fast-charging of two devices.

The 80W, folding-pin, in-box charger measures only 60 x 41 x 31 mm (76 cc), achieving a power density of over 1 W/cc and a super-lightweight 125g. The full 80W power rating is shared over the two output-ports to allow flexible, simultaneous charging of phones, tablets, audio and ultra-book laptops.

GaN is a next-generation power semiconductor technology that’s capable of running 20 times faster than traditional silicon. Compared with traditional silicon chargers, gallium nitride chargers can achieve 3x the power or 3x faster charging with up to 40% energy savings in just half the size and weight of legacy silicon solutions.

Navitas’ next-generation GaNSense technology integrates real-time, accurate and fast sensing of system parameters, including current and temperature, and achieves patent-pending, loss-less current-sensing to deliver an addition-al 10% energy savings and enables a ‘detect-to-protect’ time of only 30 ns - 6x faster than discrete GaN power chips for increased system reliability.

Commenting vivo’s Product Line General Manager Hong Yi said, “vivo is dedicated to achieve the best consumer experience on the market, including continuous breakthroughs in the charging-speed, size, and weight of the charger. Using Navitas GaN technology, this charger will bring consumers a breakthrough dual-port, faster and lighter charging experience.”
