Disassembly report: Anneng technology Ultra Mini 30W gallium nitride charger

2022-05-21

30W gallium nitride charger is the mainstream fast charging specification in the market. It has good compatibility with apple and Android phones and has a good use experience. With the blessing of gallium nitride, the volume is similar to that of 20W charger, and the shipment volume in the market is large.

Charging head network has obtained a 30W gallium nitride fast charge from Anneng technology. This charger may be the smallest 30W gallium nitride fast charge in the industry and supports 20v1 5A output, which can charge notebooks supporting PD fast charging and PPS fast charging output. It also has good compatibility with Android mobile phone fast charging. The charging head network will disassemble this charger to see how it is designed internally.

This 30W gallium nitride charger of Anneng technology is very small and light, with a white matte shell, which is not easy to wear and feel good at the same time. The charger is designed with single usb-c interface, and the output has 5v3a, 9v3a and 12V2 5A、15V2A、20V1. 5A five groups of fixed voltage gears, and support PPS fast charging at the same time. Fast charging supports all aspects.

According to the disassembly of the charging head network, this charger adopts the combination welding of two PCBs, the L-shaped structure is internally arranged with filter capacitors, transformers and other components, and the input and output capacitors are wound with tape insulation. The gallium nitride sealed chip launched by elevation is used internally, which has high integration, simplified periphery and extremely low standby power consumption.

The secondary synchronous rectifier uses the JWT synchronous rectifier controller and the IC protocol chip. The input and output adopt Yongming capacitor and the combined design of two PCBs, which has high space utilization and small volume. Solid workmanship and reliable materials.
