The dismantling is a single USB port output QC3.0 power adapter from PKJ International Co.,Ltd.
Single USB output socket, the LOGO below the socket indicates that this power supply supports QC3.0 fast charge.
Foldable mains outlet for easy carrying.
The maximum output power of this power supply is 18W from the identification of the power adapter.
As with most folding plug power supplies, the mains section uses a power cord connection to increase reliability.
The power supply PCB is front and back, the components are compact, neatly arranged, and the solder joints are full of luster.
The protection circuit and EMI circuit of the mains input section.
The primary side main capacitor uses three parallel specifications of 400V 15 microfarads, and the brand comes from Acon.
The blue capacitor is mainly used to filter out high frequency interference.
The secondary side output filter uses a 16V 680 microfarad solid capacitor.
The USB socket magnet can be sucked.
Rectifier bridge type ABS10.
The Power Integrations INN2215K IC has a controller on the primary and secondary sides. The primary side also integrates a power MOSFET. The secondary side controller monitors the output voltage and current. The information is fed back to the primary based on the monitoring results. Control to achieve more precise control of output voltage and current. Provides up to 22 W of output power.
The output synchronous rectification MOS comes from the new power, model NCEP0114AS.
QC3.0 intelligent identification IC, from EOSMEM Taiwan Converse, model NT6008B.
Use POWER-Z to detect the mode supported by this power supply, and support QC2.0 and Apple protocol while supporting QC3.0.
