Disassembly report: Gushi technology Mini 30W Gan fast charging charger

2021-07-21

Nowadays, the 20-30w Mini charger is very popular in the market. Therefore, Gushi technology recently launched ultra-thin 20W biscuit charger and 30W Mini fast charger for customers to choose. The former is designed for iPhone 12 users, small and portable, and has been disassembled in detail by the charging head network.

The 30W Mini charger is designed for other brands of mobile phones to meet the needs of users for higher power Mini chargers. This charger has two types of fixed and folding pins, which can meet the needs of different scenes such as home office and outdoor carrying. It has passed CCC, FCC, PSE and ETL certification, and can be used in major countries or regions in the world. The following charging head network on this charger for detailed disassembly, to see how to do.

Previously, Gushi 20W Mini charger, Gushi 20W biscuit fast charger, Gushi 30W USB PD charger, Gushi 18W PD charger and other products have been disassembled. In addition, there are many products for customers to choose from.

Gushi technology's Mini 30W gallium nitride charger is very small, with a bright surface on the top and a unique feel. The charger is compatible with QC, AFC, pd3.0 and PPS fast charging protocols. It has five complete voltage ranges of 5v3a, 9v3a, 12v2.5a, 15v2a and 20v1.5a, and two PPS voltage ranges of 3.3-11v3a and 3.3-16v2a. The overall compatibility is very good. It can meet the fast charging requirements of Android phones and tablets of major brands, as well as the fast charging requirements of iPhone series.

Through the disassembly of the charging head network, we learned that the charger adopts three circuit boards combined welding and U-shaped structure design. In order to improve the overall stability, the gaps between components are filled with silica gel. In addition, the filter capacitor is insulated with a plastic shell, and the small plate at the output end is hollowed out to avoid heat accumulation.

The charger adopts South core semiconductor sc3021c + sc3503 + sc2151a full set of high frequency QR gallium nitride fast charging scheme, with innoseco's second generation gallium nitride power chip inn650da04, Weizhao MOS tube synchronous rectification and output protection, emerald capacitor for input and output filtering, with reliable materials.
