Disassembly report: Xinpai technology 65W flash charging ultra-thin charger

2021-12-24

Xi'an Xinpai Electronic Technology Co., Ltd. (hereinafter referred to as Xinpai Technology) was established in 2008. It is a high-tech enterprise integrating R & D, production and sales. The products include: medium and high power field effect transistors (MOSFETs, low-voltage to high-voltage products), insulated gate bipolar transistors (IGBT), diodes (including fast recovery diodes and Schottky diodes), bridgestacks and power management ICs.

Xi'an semiconductor power device test and Application Center, the Provincial Key Laboratory of Xinpai technology, is a national CNAs & International ILAC certified laboratory and belongs to the national power device test and Application Center. In order to commemorate the 10th anniversary of the establishment of the laboratory, Xinpai technology customized a 65W flash charging ultra-thin charger as a souvenir, which was designed by Xi'an wide band gap semiconductor application research center and manufactured by Huizhou BYD Electronics Co., Ltd.

As one of the application fields of Xinpai technology products, the fast charging accessories are naturally all from Xinpai technology, which is more memorable. The charger is compact and flat, with a power density of 0.97w/cm 3。 Next, the charging head network will disassemble this souvenir in detail to see how to design it internally.

Xinpai technology 65W flash charging ultra-thin charger adopts PC flame retardant shell, with frosted surface and rounded corners. The charger is designed in cookie shape, and the three-dimensional is only 87 * 47 * 15mm. Compared with apple 61W charger, it has huge volume advantages, and the maximum output power is 65W. It is compatible with all mainstream fast charging protocols in the market, and meets the fast charging of major brands of mobile phones, tablets and laptops.

Through the disassembly of the charging head network, it is found that the internal capacitors of the charger are horizontal, and the plane transformer and sink plate design are also adopted, which is the main reason why this charger can be so thin.

The charger adopts the current common ansenmey ncp1342 + MPs mp6908a high-frequency QR switching power supply scheme. The primary switch tube sw13n65k2, synchronous rectifier tube sw069r06vt and output VBUS switch tube sw055r03vt are all products of Xinpai technology. It can be seen that Xinpai technology has the ability to provide a full range of products from low voltage to high voltage for the fast charging market. The filter capacitor comes from Aihua and emerald. The overall material and workmanship are very good.
