2021-07-05

Facing the rapid rise of the 33W Mini fast charging market, Shenzhen huakesheng Digital Technology Co., Ltd. recently launched a mini 33W fast charging for customers to choose. This product has no gallium nitride, but it can achieve 1.05w/cm power density ³， It's pretty good to say. In addition, the charger is compatible with fast charging protocol, complete voltage range, and supports PPS fast charging, which can meet the demand of most mobile phones and flat panel charging in the market. The charging head network below will be disassembled in detail to see how the charger is so small.

It is worth mentioning that huakesheng also has mini 22.5w SCP fast charging charger, 65W 2c1a Gan fast charging charger and other products available for customers to choose. The charging head network has been disassembled in detail before.

The 33W Mini charger body of huakesheng is very simple and convenient for customers to customize. The 3D is about 35 * 30 * 30MM, and the power density is more than one watt per cubic centimeter. It is very small and meets the market requirements for mini charger. In addition, the charger also has strong performance, supports qc2.0/3.0, AFC, FCP, pd3.0 and PPS fast charging protocols, has 5-20v complete voltage range, and 3.3-11v3a PPS voltage range, with good compatibility, meeting the fast charging requirements of major brands of equipment.

Through the disassembly of the charging head network, we know that the PCBA module of the charger is composed of two small boards, and the components are bonded and reinforced. The charger adopts maorui mk2697 + mk91808 high frequency QR fast charging scheme, supports output power above 65W, and is used in huakesheng 33W Mini charger to ensure reliable performance. The protocol chip adopts xpd737, Yongming kcx and NPX series small volume fast charging capacitor filter, which effectively helps the charger to achieve miniaturization.
