2021-08-17

The iPhone 12 is no longer equipped with a standard charger, which is a good event for the whole fast charging industry. Major brands have launched or upgraded relevant products in order to get a share in this huge market. Recently, maoshuo Power Technology Co., Ltd. should launch a 20W Mini charger, which can fully meet the purchase needs of customers.

The charger supports QC, PD and other fast charging protocols and PPS fast charging, which can well meet the fast charging needs of iPhone 12 series mobile phones. The following charging head network will disassemble this charger in detail to see its design and workmanship.

Maoshuo's 20W fast charging body is simple, the overall size is only 30 * 30 * 30MM, the shape tends to be "small square", which is very small and mini, meeting the current consumer demand for 20W Mini fast charging. In addition, the charger is compatible with qc2.0 / 3.0, AFC, FCP, pd3.0 and PPS fast charging protocols, and has two groups of PPS voltage gears of 3.3-5.9v3a and 3.3-11v1.8a, which can be well adapted to iPhone 12 series mobile phones to meet daily fast charging requirements.

According to the disassembly of the charging head network, the charger module is designed by stacking three small plates, and the primary components are isolated by plastic shells. The charger adopts the high integration scheme of Chengxin micro cx7527c + cx7538b, which is very helpful to product design, cost and accelerating market launch. In addition, cloud silicon semiconductor xpd720 protocol chip and Yongming small volume capacitor are also used. Thanks to the use of Chengxin micro fast charging scheme and small capacitors, the charger is so small and exquisite.
