Disassembly report: Pinsheng Mini 20W PD fast charging charger

2021-11-11

Recently, the charging head network has obtained a PISEN Pinsheng Mini 20W PD fast charging charger kpd201. Compared with the previously disassembled Pinsheng Mini 20W fast charging sk-pd20-02c, the two are similar in size and different in appearance design. It is also a good thing for the appearance party to have one more choice.

The appearance of the disassembled Mini charger kpd201 is more regular, and the square shape is very small. It supports QC, PD and other fast charging protocols and can meet the fast charging needs of iPhone 12 / 13. Let's take a look at the difference between the materials used and those disassembled before.

Previously, the charging head network also disassembled Pinsheng Mini 20W 1a1c fast charging charger sk-pd20-05d, Pinsheng 20W PD fast charging charger ts-c135, Pinsheng 65W 2c1a gallium nitride fast charging charger, Pinsheng 65W PD fast charging gallium nitride charger, Pinsheng 18W PD fast charging charger and other products. Welcome to consult.

Pinsheng's Mini 20W quick charging shape tends to be small square and adopts a white shell, so it looks very simple. The overall size is only 28 * 28 * 28mm, 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 and pd3.0 fast charging protocols, and has three groups of voltage gears: 5v3a, 9v2.22a and 12v1.67a, which can be well adapted to iPhone 12 / 13 series mobile phones to meet daily fast charging requirements.

According to the disassembly of the charging head network, the charger module is designed by a combination of two small plates, and an insulating isolation plate is set between the primary components and glued for reinforcement. The charger adopts the Chengxin micro cx7527c + cx7538b highly integrated switching power supply scheme, which can greatly simplify the circuit, which is very helpful to product design, reduce cost and speed up the market. It can also effectively help the charger reduce the volume. It is very suitable for 20W Mini fast charging.
