preface
On February 17, the game's flagship Red Devils 7 series was officially released, and brought the industry's four major debuts. Among them, in terms of charging, the 165W Gallium Nitride fast charger that is standard in the Red Devil 7 series has refreshed the power of the standard charger of mobile phones, triggering heated discussions in the industry. It is worth mentioning that the standard 165W Gallium Nitride fast charger of the Red Devil 7 series is all based on the development of Innosec GaN power devices, which is also the 8th Gallium Nitride fast charger jointly developed by Nubia and Innosec.
According to the official introduction of Red Devil, the Red Devil 7 mobile phone is equipped with a standard 4500mAh capacity battery, supporting 120W magic flash fast charge, 17 minutes to charge 100%; Red Devil 7 Pro mobile phone standard 5000mAh battery, using innovative parallel triple charge pump technology, to achieve 135W magic flash fast charge, 15 minutes can be fully charged 100%. And the application of charging separation technology, effectively realize the control of charging temperature rise, and extend the battery life.
First, Nubia 165W fast charge built-in 2 Innoseco GaN devices
The charging head network has recently carried out a deep disassembly of the 165W Gallium Nitride fast charger standard in the Red Devil 7 series, which adopts the power supply architecture of the QR flyback topology internally, and applies the power factor correction (PFC) circuit necessary for the high-power fast charging source, and the power devices of the two cores of the PFC boost switch tube and the switching power main switch tube are from Innosyco.
Among them, the gallium nitride power device for PFC boost circuit is selected by Innosec INN650D02, which is rated at 650V, peak withstand voltage of 750V, and conductance as low as 0.2Ω, which meets the industrial application requirements of the JEDEC standard, supports ESD protection, and supports Kelvin source pole. The maximum operating temperature is 150°C.
Innosec inn650D02 switch tube has good high frequency characteristics, and small on resistance, suitable for high frequency and efficient switching power supply applications, using DFN8*8 package, with ultra-low thermal resistance, good thermal performance, suitable for high power density switching power supply applications.
The power device of the AC-DC part uses Innosyco INN650D150A, which is a high-voltage single tube with a withstand voltage of 650V gallium nitride, a transient withstand voltage of 750V, a conductivity of 150mΩ, and a DFN8*8 package.
Innosec inn650D150A supports ultra-high switching frequencies, no reverse recovery charge, very low gate charge and output charge, meets the requirements of JEDEC standards for industrial applications, has built-in ESD protection, and complies with RoHS, lead-free, EU REACH regulations.
It is worth mentioning that the INN650D02 and INN650D150A switch tubes are based on the industry-leading 8-inch production and processing technology, which is currently the first mass-produced advanced process Gallium nitride power device on the market, and the large-scale commercial use of this technology will promote the rapid popularization of gallium nitride fast charging.
Second, Innosec has helped Nubia develop several gallium nitride fast charging
In recent years, gallium nitride and high-power fast charging has become the focus of the current power market, and as the industry's leading 8-inch gallium nitride power device original, Innosecco has achieved a certain share in the high-power gallium nitride fast charging source market, but also the first domestic into the mobile phone / laptop manufacturer GaN fast charging source supply chain enterprises, the performance of the device has been highly recognized by the industry. Among them, Nubia alone has developed 8 ganide fast chargers with Innocent.
