65W GaN chargers customized as Transformers movie characters
Integrated GaN power chips from Navitas Semiconductor are at the heart of a series of Transformers-branded custom 65W chargers from GravaStar.
The three port Alpha65 gallium nitride (GaN) chargers have two USB-C ports and one USB-A, marking a shift to the newer connector standard to charge three devices such as laptops, cellphones, tablets or earbuds up to the 65W limit.
The 128g, 58 x 35 x 55 mm (112 cc) design is achieved by Navitas’ GaNSense Control which integrates a low-voltage silicon system controller with a high-voltage, monolithically-integrated GaN power IC. For the Alpha65, the NV9580 QR-flyback primary device is matched with the NV9701 IC for high-frequency secondary rectification.
The hand-polished chargers are designed as pet robots, with 360° rotating magnetic antenna and 45° foldable legs for more playability and are inspired by two popular Transformers characters – Optimus Prime and Bumblebee, in blue and yellow. Each charger ‘transforms’ 4x bigger, to 84.5 x 60 x 89 mm (451 cc) with extended antennas and legs.
“GravaStar provides consumers with trendy and innovative 3C products. The Alpha Transformers design is not only a high-speed GaN charger but also an exquisite collectible for Transformers fans worldwide.” said Gravistar founder and Chief Product Manager, Mr. Huang Yong. “The partnership with Navitas let us witness the enormous potential of GaNSense Control. We’re looking forwarding to deeper collaboration with Navitas to introduce more, next-generation power devices.”
“Navitas is delighted that we helped GravaStar present Alpha 65W charger as a gift to Transformers fans. The success of the Alpha Transformer charger has sparked our imagination for the future of charger design, with confidence derived from the high level of integration and valuable features of Navitas’ GaNSense Control,” said Charles Zha, VP and GM of Navitas China.
