Hi, guys. Welcome back to our channel.
We haven’t teardown Anker’s charger for a while.
And today, we gonna tear down a customized charger for League of Legends.
It’s actually the brand new 65W 3-Port Charger of PowerPort III series.
You can check it out in the description.
The packaging is dark blue.
And there’re some selling points and specs information on the back.
Open the box.
And we can see the black charger and its matte surface.
The blue Anker logo is on this side. And the Yasuo is on the other side.
It’s equipped with two USB-C and one USB-A.
So you can charge three devices at the same time.
It also adopts folding pins, which is convenient to use.
Then, let’s take a look at those specs information.
Model is A9521.
It supports input of 100-240V~50/60HZ 1.5A.
As for the output information. You can pause to take a look.
Compared with Apple 61W charger. The size is almost half of it.
The size of the charger is 33*37*72mm (1.3*1.46*2.83 inches).
So, the power density is 0.71W/cm³.
The weight is around 124g (4.37 oz).
Use ChargerLAB POWER-Z KT002 to test the protocol.
USB-A supports Apple 2.4A, Samsung 5V2A, DCP protocols
and QC2.0/3.0, AFC, FCP, SCP, VOOC/DASH/WARP, PE2.0 fast charging protocols.
USB-C supports Apple 2.4A, Samsung 5V2A, DCP protocols
and QC2.0/3.0, AFC, FCP, SCP, PE2.0, PD3.0, PPS multiple fast charging protocols.
It has five fixed PDOs of 5V3A, 9V3A, 12V3A, 15V3A, 20V3.25A,
and one PPS of 3.3-11V5A.
The protocols and PDO information of USB-C2 are the same as C1.
Use the spudger to pry the shell along the gap.
We can see the pins are connected to the PCB through a wire.
The internal module is also wrapped with heat sink.
And the insulation plate is placed between the heat sink and components.
Remove the heat sink.
And the thermal pad is under the insulation plate to enhance heat dissipation.
Remove the insulation plate.
Then we can see a lot of thermal adhesives between front components.
ChargerLAB found this charger adopts the high-frequency QR flyback architecture.
The switching power supply adopts GaN IC and can output fixed voltage.
Then, two independent secondary step-down circuits can output different voltages.
Then, let’s start from the input to analyze every single component.
The specs of time-delay fuse is 250V 3.15A.
There are two common mode chokes and a safety X2 capacitor on the input PCB.
And there’re four resistors.
Two bridge rectifiers are on the front of the PCB, used to dissipate heat evenly.
Three electrolytic capacitors for high-voltage filtering come from CapXon.
400V 33μF.
The master control chip comes from ON Semiconductor NCP1342,
which is a highly integrated quasi−resonant flyback controller.
It integrates active X2 capacitor discharge feature and has complete protection functions.
The primary switch transistor adopts Navitas NV6115,
which adopts 5*6mm QFN package.
This is a GaN IC, which integrates independent driver and complex logic control circuit.
The specs of the GaN FET inside are 170mΩ, 650V.
It also supports 5-15V input and 2MHz switching frequency.
Here is the transformer.
There is an optocoupler between the primary and secondary circuit,
used to feed back output voltage.
The blue Y capacitor is used for output anti-interference.
The synchronous rectifier controller comes from MPS MP6908A.
The operating frequency can reach 600KHz.
The synchronous rectifier comes from Hunteck HGN070N12S,
which adopts DFN 5x6 package.
120V, 6mΩ.
The solid capacitor for output filtering comes from APAQ.
25V 680μF.
The secondary step-down controller comes from Ismartware SW3518S,
used to control step-down output and protocol recognition of USB-C2 and USB-A.
It can support multiple protocols and has passed VOOC certification.
Those two MOSFETs are controlled by the previous chip,
used for synchronous step-down and outputting the required voltage.
The output VBUS MOSFET comes from Ruichips RU30D20.
Its withstand voltage is 30V and packaged by PDFN3333.
This is the step-down circuit of USB-C1. We can see step-down inductor, filter capacitor,
filter inductor, control chip are on the front.
Two MOSFETs and an MCU are on the back.
Here is the USB-C1 controller, used for the step-down control and protocol identification of USB-C1.
Model is Ismartware SW3516H.
The solid capacitor for output filtering of USB-C1
also comes from APAQ. 25V 220μF.
Here is the USB-C1.
Because of the particular pin inside, the USB-A can support VOOC protocol.
Here is the USB-C2.
Well, that’s all components of this Anker 65W three-ports charger.
Because of two independent step-down circuits and three ports,
you can easily charge most of your devices at the same time.
It also supports multiple charging protocols,
and both USB-C can support maximum output of 65W.
So, you can choose any port.
OK, that’s all for today’s video.
