QC and PD fast charging are the most popular fast charging standards, which are widely used in mobile phones, tablets, pen phones and other devices. As time goes on, these two fast charging standards are constantly developing. On July 27 last year, Qualcomm released the new generation of qc5 fast charging protocol, namely the latest qc5. The maximum charging power is up to 100W +, which is 70% higher than qc4 efficiency. The charging speed is increased by four times, and the heating temperature is reduced by 10 degrees.As a new generation of fast charging protocol, the major fast charging chips, fast charging products and mobile devices are competing to pass its certification. In terms of fast charging products, the well-known brand baseus Beisi took the lead in launching the world's first qc5100w fast charging Gan charger. At the same time, the charger is also downward compatible with qc2.0, qc3.0 and other fast charging protocols. Next, the charging head network will disassemble this new qc5 fast charging product in detail, and let's have a look at its design materials.Prior to that, the charging head network also successively disassembled several kinds of Gan fast charging products, such as Beisi 120W 2c1a Gan fast charging charger, Beisi 100W 2a2c Gan fast charging charger, Beisi 65W 2C Gan fast charging charger gan2 Lite, Beisi 65W 2c1a Gan fast charging charger, Beisi 45W 1a1c Gan fast charging charger, and Beisi dual usb-c port 45W Gan fast charging charger, You can click the blue font for reference.As another 100W level Gan fast charger of Beisi, it continues the previous 100W multi port charger appearance ID design of Beisi. The body is also printed with 100W special font. In addition, the charger adopts foldable pin design to ensure portability. The product is equipped with a single usb-c interface, supports the latest qc5 fast charging of Qualcomm, and also supports qc2.0/3.0, pd3.0 and PPS fast charging protocols. It has 5 / 9 / 12 / 15v3a, 20v5a and 3.3-20v5a voltage ranges, which fully meets the fast charging requirements of mobile phones, laptops and other devices.Through the disassembly of the charging head network, we know that the components on the PCBA module are well planned and orderly, and there are no less conventional designs such as gluing and heat sink. In addition, as a high-power charger, PFC boost circuit is indispensable. The boost switch adopts nano micro nv6125 Gan power chip.The switching power supply is composed of Anson ncp1342 with Dongwei high voltage MOS transistor, and maorui mk91808 with hengtaike synchronous rectifier, which outputs a wide range of voltage. The output voltage is controlled by high performance protocol IC of ip2726s qc5. The whole product is made of solid materials.
