2021-05-17

Recently, move speed has launched a 20W PD fast charging Mini charger, model ysfcp101-20w, which also has a nice name - elf. This product supports QC, PD, PPS and other fast charging protocols, and can meet the full speed fast charging requirements of iPhone 12. It also has good compatibility with other brands of Android. The charging head network will disassemble it to see how the materials are made.

Not long ago, the charging head network also disassembled another type of 20W PD fast charging charger. You can click the blue font to check it.

This 20W Mini charger is compact and simple, equipped with fixed pins and a single C port. In addition to supporting QC and PD general fast charging protocol, it also supports pe2.0 and PPS fast charging protocol. It has two PPS voltage ranges of 3.3-5.9v3a and 3.3-11v2a, with good overall compatibility, and can meet the daily charging needs of major brands of mobile phones.

It is learned from the disassembly of charging head network that the charger adopts the popular design of combination and welding of multiple small plates, and adopts the full set of fast charging power supply scheme of Anbao ob2631u + ob2004z + ob2613, with few peripheral components and very simple circuit. in addition

Junkang electrolytic capacitor, fushida and Yubang solid-state capacitor are used for input and output filtering, and the main material is used. The capacitor is insulated, and the area where the synchronous rectifier chip is located is exposed copper and tin to enhance heat dissipation.
