Navitas Semiconductor announced that its gallium nitride (GaN) power ICs are being used in the Xiaomi 55W fast charger (model MDY-12-EQ), supplied ‘in-box’ with every Mi 11 smartphone.
The Mi 11 is the first smartphone with the Qualcom Snapdragon 888 5G processor, has a Gorilla Glass 6.81″ AMOLED screen with 1440p resolution, plus a large 4,600 mAhr battery. Using the GaNFast 55W, the Mi 11 charges from 0-100% in only 45 minutes, half the time of competitor flagships, and is also highly compact at half-the size of typical silicon-based chargers.
Gallium nitride (GaN) is a next-generation semiconductor technology that runs up to 20x faster than old, slow silicon (Si), and enables up to 3x more power or 3x faster charging in half the size & weight. GaNFast power ICs integrate GaN power and drive plus protection and control to deliver the simplest, smallest, fastest and now even higher-power performance.
The Xiaomi 55W fast charger uses an NV6115 GaNFast power IC in a high-frequency quasi-resonant (HQFR) flyback converter with the On Semiconductor NCP1342 controller at 200kHz to enable a slimline, planar transformer with shrunk core, plus smaller EMI filter and output capacitors.
“One of the best things about the 55W GaN charger is that it capable of charging more of your gear, including laptops, gaming consoles and smartphones”, said Mr Shou Zi CHEW, Partner, Senior Vice President and President of International, Xiaomi Corporation in the Mi 11 launch video. “We believe this is truly a world-class charging experience,” he added.
“Following the Mi 10 accessory GaNFast charger in February 2020 and the excitement over our ‘Little Star’ GaN twins at the Xiaomi Technology & Investment Day in October, we are now very excited to go global with Xiaomi with the Mi 11 55W ‘in-box’ GaNFast charger, now with the European 2-pin AC option,” said Gene SHERIDAN, Navitas CEO and co-founder. “This is a major commitment to mainstream adoption of gallium nitride technology and the beginning of the end for the old, slow silicon chip,” he added.
