Disassembly report: iqoo 10 Pro original 200W gallium nitride ultra fast flash charge

2023-08-09

On July 19, iqoo 10 series new phones were released, all equipped with the latest Qualcomm snapdragon 8+ mobile platform and self-developed chip v1+ to help improve the image. It is a flagship phone with a significantly improved experience, and also refreshed the list of fast charging in the mobile phone industry.

Iqoo 10 Pro is the first commercial 200W ultra fast flash charging mobile phone produced in mass. With the original gallium nitride Mini charger, it only takes 10 minutes to fill the built-in 4700mah high-capacity battery, leading a new era of smart phone charging. The charging head network has obtained this 200W gallium nitride flash charge. Now let's disassemble it to see how the interior is designed.

The 200W gallium nitride flash charge launched by iqoo has two nano nv6136a gallium nitride power chips built in. Compared with the 120W gallium nitride flash charge launched before, the volume is only slightly increased, and the power density is significantly improved. This charger supports 200W ultra fast flash charging and 65W general PD output, as well as 5-20v3.25a PPS output. It can also be used to quickly charge notebooks and other mobile phones, and its versatility is also good.

The charging head network learned through disassembly that the 200W gallium nitride charger iqoo adopts pfc+zvs flyback circuit architecture, the PFC boost controller adopts ansenmey ncp1623, the ZVS flyback controller adopts dialog iw9802, and the nano gallium nitride power chip nv6136a. The synchronous rectifier controller adopts MPs mp6908a, and the synchronous rectifier uses two vsp003n10hs-g of Weizhao semiconductor in parallel to meet the 10A high current output.

Aihua electrolytic capacitor and solid-state capacitor filter are used inside the charger. The transformer and switch tube are pasted with thermal conductive pads to strengthen heat dissipation and reduce the temperature rise of high-power output. Multiple thermistors are equipped inside the charger to detect the temperature, and the monitoring temperature does not exceed the normal range to ensure safe use.
